Telegram founder and CEO Pavel Durov was arrested Saturday night by French authorities on allegations that his social media platform was being used for child pornography, drug trafficking and organized crime. The move sparked debate over free speech worldwide from prominent anti-censorship figures including Elon Musk, Robert F. Kennedy. Jr. and Edward Snowden. However, "the immediate freakout came from Russia," reports Politico. "That's because Telegram is widely used by the Russian military for battlefield communications thanks to problems with rolling out its own secure comms system. It's also the primary vehicle for pro-war military bloggers and media -- as well as millions of ordinary Russians." From the report: "They practically detained the head of communication of the Russian army," Russian military blogger channel Povernutie na Z Voine said in a Telegram statement. The blog site Dva Mayora said that Russian specialists are working on an alternative to Telegram, but that the Russian army's Main Communications Directorate has "not shown any real interest" in getting such a system to Russian troops. The site said Durov's arrest may actually speed up the development of an independent comms system. Alarmed Russian policymakers are calling for Durov's release.

"[Durov's] arrest may have political grounds and be a tool for gaining access to the personal information of Telegram users," the Deputy Speaker of the Russian Duma Vladislav Davankov said in a Telegram statement. "This cannot be allowed. If the French authorities refuse to release Pavel Durov from custody, I propose making every effort to move him to the UAE or the Russian Federation. With his consent, of course." Their worry is that Durov may hand over encryption keys to the French authorities, allowing access to the platform and any communications that users thought was encrypted.

French President Emmanuel Macron said Monday that the arrest of Durov was "in no way a political decision." The Russian embassy has demanded that it get access to Durov, but the Kremlin has so far not issued a statement on the arrest. "Before saying anything, we should wait for the situation to become clearer," said Kremlin spokesperson Dmitry Peskov. However, officials and law enforcement agencies were instructed to clear all their communication from Telegram, the pro-Kremlin channel Baza reported. "Everyone who is used to using the platform for sensitive conversations/conversations should delete those conversations right now and not do it again," Kremlin propagandist Margarita Simonyan said in a Telegram post. "Durov has been shut down to get the keys. And he's going to give them."

Stephen Wolfram, renowned mathematician and computer scientist, is calling for philosophers to engage with critical questions surrounding AI as the technology's advancement raises complex ethical and societal issues. Wolfram, creator of Mathematica and Wolfram Alpha, argues that the tech industry's approach to AI development often lacks philosophical rigor. "Sometimes in the tech industry, when people talk about how we should set up this or that thing with AI, some may say, 'Well, let's just get AI to do the right thing.' And that leads to, 'Well, what is the right thing?'"

He sees parallels between current AI challenges and foundational questions in philosophy, citing discussions on AI guardrails and the potential for AI to significantly impact society as examples where philosophical inquiry is crucial. The scientist, who earned his doctorate at 20, suggests that philosophers may be better equipped than scientists to tackle the paradigm shifts AI presents. Wolfram's call comes as AI's growing influence raises ethical concerns across industries, urging an interdisciplinary approach to address these emerging challenges.

Microsoft has retracted or clarified its statement regarding the deprecation of Windows Control Panel, according to changes made to a support document. The original text, which stated that the Control Panel was "in the process of being deprecated in favor of the Settings app," has been revised. The new version now indicates that "many of the settings in Control Panel are in the process of being migrated to the Settings app." This modification came after widespread media coverage of the initial announcement. It remains unclear whether this change reflects a shift in Microsoft's plans or a correction of an erroneous statement.

The Register's Iain Thomson reports: The FBI has made serious slip-ups in how it processes and destroys electronic storage media seized as part of investigations, according to an audit by the Department of Justice Office of the Inspector General. Drives containing national security data, Foreign Intelligence Surveillance Act information and documents classified as Secret were routinely unlabeled, opening the potential for it to be either lost or stolen, the report [PDF] addressed to FBI Director Christopher Wray states. Ironically, this lack of identification might be considered a benefit, given the lax security at the FBI's facility used to destroy such media after they have been finished with.

The OIG report notes that it found boxes of hard drives and removable storage sitting open and unattended for "days or even weeks" because they were only sealed once the boxes were full. This potentially allows any of the 395 staff and contractors with access to the facility to have a rummage around. To deal with this, the FBI is installing wire cages to lock away storage media. In December, the bureau said it would install a video surveillance system at the evidence destruction storage facility to tighten security. As of June this year, it was still processing the paperwork to do so. The OIG also found that FBI agents aren't tracking hard drives and removable storage sent into the central office and the destruction facility. Typically, seized computers are tagged for tracking, but as a cost-saving measure, agents are advised to send in media storage devices containing national security information without the chassis. While there is a requirement to tag removable storage, there isn't the same requirement for internal hard drives. [...]

The FBI has assured the regulator that it has the problem in hand and has drafted a Physical Control and Destruction of Classified and Sensitive Electronic Devices and Material Policy Directive, which will require data to be marked up and destroyed safely. The agency says this policy is in the final editing stage and will be issued as soon as possible.

An anonymous reader quotes a report from CBC.ca: Prime Minister Justin Trudeau announced Monday Canada will impose punitive tariffs on Chinese-made electric vehicles -- copying a similar initiative that the U.S. is already pursuing to stop a flood of what's been described as unfairly state-subsidized cars. Trudeau made the announcement at the federal cabinet retreat in Halifax where ministers are meeting to craft a strategy for the year ahead -- the last year before an expected federal election in October 2025. Amid industry pressure to copy the U.S. program, Trudeau said a 100 percent surtax will be levied on all Chinese-made EVs, effective Oct. 1. The tariff would effectively double the price of imported vehicles, as it is expected most of the tax would be passed on to consumers.

Ottawa is following through now, Trudeau said, to "level the playing field for Canadian workers" and allow Canada's nascent EV industry to compete at home, in North America and globally. The tariff will apply to electric and certain hybrid passenger automobiles, trucks, buses and delivery vans. Chinese brands like BYD are not a major player in Canada's EV market right now but imports from China have exploded in recent years as Tesla switched from U.S. factories for its Canadian sales to its manufacturing plant in Shanghai. The new tariff will apply to those Shanghai-made Teslas that are sold in Canada -- a development that is expected to force the U.S. automaker to supply the Canadian market with vehicles made at one if its other plants in the U.S. or Europe instead. "Unfortunately, Canada made a decision today that will result in fewer affordable electric vehicles for Canadians, less competition and more climate pollution," said Joanna Kyriazis, director of public affairs at Clean Energy Canada. "Not only could today's announcement have a chilling effect on future EV sales, it could drive up EV prices and slow adoption in the near-term as well," Kyriazis said.

Flavio Volpe, the president of the Automotive Parts Manufacturers' Association who lobbied Ottawa to follow through with matching the U.S. tariffs, responded: "Sure, what the Chinese are doing is selling us green products that help fulfill some of our EV mandates, but they do it in a regulatory environment where they forgo any stewardship of the environment," he said.

Deputy Prime Minister Chrystia Freeland added that the Chinese industry is "built on abysmal labour standards and it is built on abysmal environmental standards."

OpenAI said in a letter that it supports California bill AB 3211, which requires tech companies to label AI-generated content. Reuters reports: San Francisco-based OpenAI believes that for AI-generated content, transparency and requirements around provenance such as watermarking are important, especially in an election year, according to a letter sent to California State Assembly member Buffy Wicks, who authored the bill. "New technology and standards can help people understand the origin of content they find online, and avoid confusion between human-generated and photorealistic AI-generated content," OpenAI Chief Strategy Officer Jason Kwon wrote in the letter, which was reviewed by Reuters.

AB 3211 has already passed the state Assembly by a 62-0 vote. Earlier this month it passed the senate appropriations committee, setting it up for a vote by the full state Senate. If it passes by the end of the legislative session on Aug. 31, it would advance to Governor Gavin Newsom to sign or veto by Sept. 30.

Apple is expected to launch the iPhone 16 lineup on September 9th, 2024, at 1PM ET / 10AM PT. The tech giant sent out invitations to the event today with the tagline: "It's Glowtime" -- a reference to the redesigned Siri with Apple Intelligence. The Verge reports: The big change to the iPhone 16 and 16 Plus is expected to be a switch to a vertically aligned camera system on the back. (If the final phones look like what we've seen on iPhone 16 dummy units, I'm already a big fan of this change.) The iPhone 16 Pro and 16 Pro Max phones might get bigger screens but are rumored to keep Apple's familiar three-camera layout. Those phones could also come in a new bronze color.

All four iPhone 16 models are expected to have the Action Button, which was exclusive to the Pro line with the iPhone 15. Apple's new iPhones may also have a new button dedicated to capturing photos and videos, but it's unclear if that will be a Pro-exclusive feature or will be available on the regular iPhone 16 models as well. AI and the company's Apple Intelligence features will likely be a big part of Apple's event, too.

An anonymous reader quotes a report from the Financial Times: Ikea is taking on the likes of eBay, Craigslist, and Gumtree with a peer-to-peer marketplace for customers to sell secondhand furniture to each other. Ikea Preowned will be tested in Madrid and Oslo until the end of the year with the aim of rolling out the buying and selling platform globally, according to Jesper Brodin, chief executive of Ingka, the main operator of Ikea stores. [...] Ikea has had a small offering under which it buys used furniture from customers and resells it in store. But the new platform is more ambitious, aiming to tackle the secondhand market for customers selling directly to each other -- an area where Brodin estimates Ikea has a higher market share than in new furniture sales. Customers enter their product, their own pictures, and a selling price, while Ikea's own artificial intelligence-enabled database brings in its own promotional images and measurements. The buyer collects the furniture directly from the seller, who has the option of receiving money or a voucher from Ikea with a 15 percent bonus.

"Very often there is a monopoly or oligopoly on platforms that operate," said Brodin, talking about eBay or digital classified ad services such as Gumtree in the UK and Finn in Norway. Finn has 8,700 items from Ikea listed in Oslo alone. Early offerings on Ikea Preowned include large items such as sofas for up to $670 (600 euros) and wardrobes for $500 (450 euros) as well as smaller items such as a toilet roll holder for $4.50 (4 euros). Listings are free, but Brodin said Ikea could eventually charge "a symbolic fee, a humble fee." He added: "We're going to verify the full scope including the economics. If a lot of people use the offer to get a discount with Ikea -- it's a good way to reconnect with customers. I am very curious. I think it makes business sense." Ikea has previously tested selling its new furniture on third-party platforms such as Alibaba's Tmall in China, but the Preowned platform marks its first foray into secondhand marketplaces. It also dovetails with the retailer's wish to become "circular and climate positive" by 2030.

An anonymous reader shares a report: OpenAI lacks advanced security and customer support. It's just a research company, not an established cloud provider. The ChatGPT-maker is not focused enough on corporate customers. These are just some of the talking points Amazon Web Services' salespeople are told to follow when dealing with customers using, or close to buying, OpenAI's products, according to internal sales guidelines obtained by Business Insider. Other talking points from the documents include OpenAI's lack of access to third-party AI models and weak enterprise-level contracts. AWS salespeople should dispel the hype around AI chatbots like ChatGPT, and steer the conversation toward AWS's strength of running the cloud infrastructure behind popular AI services, the guidelines added.

[...] The effort to criticize OpenAI is also unusual for Amazon, which often says it's so customer-obsessed that it pays little attention to competitors. This is the latest sign that suggests Amazon knows it has work to do to catch up in the AI race. OpenAI, Microsoft, and Google have taken an early lead and could become the main platforms where developers build new AI products and tools. Though Amazon created a new AGI team last year, the company's existing AI models are considered less powerful than those made by its biggest competitors. Instead, Amazon has prioritized selling AI tools like Bedrock, which gives customers access to third-party AI models. AWS also offers cloud access to in-house AI chips that compete with Nvidia GPUs, with mixed results so far.

Pavel Durov, the Russian-born billionaire co-founder of the Telegram messaging app, was arrested in France in connection with an investigation into criminal activity on the platform and a lack of cooperation with law enforcement, prosecutors announced on Monday. From a report: Durov, who has French citizenship, was detained at Le Bourget airport, just outside Paris, on Saturday evening after arriving from Azerbaijan on his private jet. His surprise arrest has sparked debate over free speech worldwide and led to an outcry in Moscow. The Paris prosecutor Laure Beccuau said the investigation concerned crimes related to illicit transactions, child sexual abuse, fraud and the refusal to communicate information to authorities.

Earlier in the day the French president, Emmanuel Macron, gave the first confirmation that Durov had been arrested as part of a judicial inquiry in relation to Telegram. "In a state governed by the rule of law, freedoms are upheld within a legal framework, both on social media and in real life, to protect citizens and respect their fundamental rights," Macron wrote on X, adding that the arrest was "in no way a political decision." "It is up to the judiciary, in full independence, to enforce the law," he said. A senior official at Ofmin, a French agency set up last year to prevent violence against children, said Durov's arrest was linked to Telegram's failure to properly fight crime on the app, including the spread of child sexual abuse material.

Car buyers are increasingly skeptical of advanced automotive technologies, a new JD Power survey reveals. The study found that while drivers appreciate practical innovations like blind spot monitoring, they see little value in features such as automatic parking systems and passenger-side infotainment screens. The survey measured user experiences with new vehicle technologies. Results show that systems partially automating driving tasks had low perceived usefulness, aligning with recent Insurance Institute for Highway Safety data indicating no safety improvements from such features. The survey identified AI-based smart climate control as popular among users. However, facial recognition, fingerprint scanners, and gesture controls were largely viewed negatively.

Millions of Australians just got official permission to ignore their bosses outside of working hours, thanks to a new law enshrining their "right to disconnect." From a report: The law doesn't strictly prohibit employers from calling or messaging their workers after hours. But it does protect employees who "refuse to monitor, read or respond to contact or attempted contact outside their working hours, unless their refusal is unreasonable," according to the Fair Work Commission, Australia's workplace relations tribunal. That includes outreach from their employer, as well as other people "if the contact or attempted contact is work-related."

The law, which passed in February, took effect on Monday for most workers and will apply to small businesses of fewer than 15 people starting in August 2025. It adds Australia to a growing list of countries aiming to protect workers' free time. "It's really about trying to bring back some work-life balance and make sure that people aren't racking up hours of unpaid overtime for checking emails and responding to things at a time when they're not being paid," said Sen. Murray Watt, Australia's minister for employment and workplace relations. The law doesn't give employees a complete pass, however.

theodp writes: Typos happen to the best of us, but spelling still counts when it comes to software development. So, it's kind of surprising to see that both Amazon CEO Andy Jassy and former AWS CEO Adam Selipsky failed to notice an embarrassing typo in a demo video they offered to their millions of followers on social media as evidence of Amazon Q AI's Java upgrade capabilities, which Amazon has been trumpeting for months in SEC filings, shareholder communication, and Amazon's latest earnings call with Wall Street analysts.

Just 37 seconds into the demo of the software that Amazon says saved it 4,500 developer-years of work and provided an additional $260M in annualized efficiency gains, Amazon Q kicks off the Java upgrade conversation by saying, "I can help you upgrade your Jave [sic] 8 and 11 codebases to Java 17." The embarrassing misspelling did prompt Twitter user @archo5dev to alert Jassy to the typo, but there's been no response yet from Jassy, who boasted that Amazon developers were unable to find any mistakes in Q's work in "79% of the auto-generated code reviews."

It's probably worth noting that both Jassy and Selipsky opted to showcase a drop-dead simple demo of Amazon Q Code Transformation rather than some of the lengthier and less-magical demos of the product.

President Emmanuel Macron said Monday that the French government was not involved in the arrest of Telegram founder and CEO Pavel Durov. From a report: "The arrest of Telegram's president on French territory took place as part of an ongoing judicial investigation. This is in no way a political decision. It is up to the judges to decide," Macron said. Durov was detained Saturday night after his private jet arrived in Paris. The Paris prosecutor has not yet communicated the reasons for the arrest of Durov, who founded the messaging app in 2013.

The tech chief currently remains in policy custody. The arrest follows probes "accusing Telegram of being complicit in numerous affairs linked to drug trafficking, apology for terrorism and cyberbullying," French daily Le Monde reported. In a statement, Telegram said that its CEO -- a Russian-born French-Emirati citizen -- had "nothing to hide" and that the company abided by EU law.

[...] "More than anything else, France is committed to freedom of expression and communication, innovation and entrepreneurship," Macron said Monday. "In a state governed by the rule of law, on social networks as in real life, freedoms are exercised within a framework established by law to protect citizens and respect their fundamental rights."

IBM is the latest American company to downsize its presence in China amid heightened tensions between Washington and Beijing. From a report: China's efforts to decrease its dependence on the West have ratcheted up local market competition -- and U.S. tech giants including Microsoft are looking elsewhere to house their operations. IBM will shut down its research and development department in China, impacting about 1,000 jobs, multiple outlets reported Monday.

The Chinese government has encouraged domestic companies to overtake and push out U.S. tech dominance out of the country in a bid for self-sufficiency in the sector, the Wall Street Journal reported earlier this year. IBM has faced mounting competition in China in recent years, IBM executive Jack Hergenrother told employees virtually Monday, per the Journal. IBM reportedly plans to move its R&D operations to other overseas facilities. According to the company's 2023 annual report released earlier this year, the company saw its revenue in China drop 19.6% last year.

Messaging app Telegram has said its CEO Pavel Durov, who was detained in France on Saturday, has "nothing to hide." From a report: Mr Durov was arrested at an airport north of Paris under a warrant for offences related to the app, according to officials. The investigation is reportedly about insufficient moderation, with Mr Durov accused of failing to take steps to curb criminal uses of Telegram. The app is accused of failure to co-operate with law enforcement over drug trafficking, child sexual content and fraud.

Telegram said in a statement that "its moderation is within industry standards and constantly improving." The app added: "It is absurd to claim that a platform or its owner are responsible for abuse of that platform." Telegram said Mr Durov travels in Europe frequently and added that it abides by European Union laws, including the Digital Services Act, which aims to ensure a safe and accountable online environment. "Almost a billion users globally use Telegram as means of communication and as a source of vital information," the app's statement read. "We're awaiting a prompt resolution of this situation. Telegram is with you all." Judicial sources quoted by AFP news agency say Mr Durov's detention was extended on Sunday and could last as long as 96 hours.

This weekend NASA said they'd turn to SpaceX to return two astronauts from the International Space Station, notes the Associated Press, "rather than risk using the Boeing Starliner capsule that delivered them." (They add that Boeing's capsule "has been plagued by problems with its propulsion system.")

But Reuters reported that even before the setback, Boeing and Lockheed Martin were "in talks to sell their rocket-launching joint venture United Launch Alliance to Sierra Space, two people familiar with the discussions said." A deal to sell ULA, a major provider of launch services to the U.S. government and a top rival to Elon Musk's SpaceX, would mark a significant shift in the U.S. space launch industry as ULA separates from two of the largest defense contractors to a smaller, privately held firm.

The potential sale comes after years of speculation about ULA's future and failed attempts to divest the joint venture over the past decade. In 2019, Boeing and Lockheed Martin reportedly explored selling ULA but couldn't agree on terms with potential buyers... Jeff Bezos' Blue Origin and Cerberus Capital Management had placed bids in early 2023 for the company, according to people familiar with the negotiations. Rocket Lab had also expressed interest, two people said. None of those discussions led to a deal...

A potential deal could accelerate deployment of [Sierra Space's] crewed spaceflight business, analysts said. A ULA acquisition, they said, would give the company in-house access to launch vehicles that could send its spaceplane and space-station components into Earth's orbit, rather than spending hundreds of millions of dollars for those launches as a customer...

ULA has faced challenges in scaling Vulcan production and upping its launch rate to meet commercial demand and fulfill contract obligations with the Space Force, which in 2021 picked Vulcan for a sizable chunk of national security missions alongside SpaceX's Falcon fleet. A sale of ULA would unshackle the company from Boeing and Lockheed, whose boards have long resisted ideas from ULA to expand the business beyond rockets and into new competitive markets such as lunar habitats or maneuverable spacecraft, according to former executives.
While Reuters's sources say the negotiations could still end without a deal, they also said ULA could be valued between $2 billion and $3 billion, giving Boeing some cash while shifting its focus to its core businesses of aerospace and defense.

Google may be the most successful company in the world. But a Washington Post reporter argues that Google "makes you largely responsible for dodging the criminals who are hurting legitimate businesses and swindling people." On Monday, I found what appeared to be impostors of customer service for Delta and Coinbase, the cryptocurrency company, in the "People also ask" section high up in Google. A group of people experienced in Google's intricacies also said this week that it took about 22 minutes to fool Google into highlighting a bogus business phone number in a prominent spot in search results...

If you look at the two impostor phone numbers in Google for Delta and Coinbase, there are red flags. There are odd fonts and a website below the bogus numbers that wasn't for either company. (I notified Google about the apparent scams on Monday and I still saw them 24 hours later.) The correct customer help numbers did appear at the very top, and Google says businesses have clear instructions to make their customer service information visible to people searching Google.
The larger issue is "a persistent pattern of bad guys finding ways to trick Google into showing scammers' numbers for airlines, hotels, local repair companies, banks or other businesses." The toll can be devastating when people are duped by these bogus business numbers. Fortune recently reported on a man who called what a Google listing said was Coinbase customer support, and instead it was an impostor who Fortune said tricked the man and stole $100,000...

Most of the time, you will find correct customer service numbers by Googling. But the company doesn't say how often people are tricked out of time and money by bogus listings — nor why Google can't stop the scams from recurring.
The article makes two points.

• Google says when they identify listings violating their rules, they move quickly against them.

• "Impostor numbers pop up so persistently that I am once again begging you to be wary of Google or Google Maps listings for business phone numbers... You still might see bogus phone numbers in some spots in Google. And if you're stressed trying to find help with a flight or a financial problem, you might overlook warning signs. Scams work because humans make errors in judgment, especially when we're confused or panicky. And business impostors aren't always obvious."

To build the massive datacenters generative AI requires, major companies like Amazon and Microsoft "are going nuclear," reports CIO magazine. AWS: Earlier this year, AWS paid $650 million to purchase Talen Energy's Cumulus Data Assets, a 960-megawatt nuclear-powered data center on site at Talen's Susquehanna, Pennsylvania, nuclear plant, with additional data centers planned — pending approval by the Nuclear Regulatory Agency... In addition to its purchase of the Cumulus data center, AWS will have access to nuclear energy as part of a 10-year Power Purchase Agreement (PPA) from the Susquehanna site.
Microsoft: Last year, Constellation signed a deal giving Microsoft the rights to receive up to 35% of its power from nuclear sources in addition to its existing solar and wind purchases from Constellation for Microsoft's Boydton, Va., data center. Microsoft has also signed a nuclear carbon credits deal with Ontario Power Generation for its operations in Canada.
The broader industry: Many of the deals under discussion are with existing nuclear power providers for hyperscalars [large-scale datacenters] to access energy or to employ small module nuclear reactors (SMRs) with smaller carbon footprints that will be annexed to existing nuclear power plants. Nucor, Oklo, Rolls-Royce SMR, Westinghouse Electric, Moltex Energy, Terrestrial Energy, General Electric, Hitachi Nuclear Energy, and X-energy are among the roster of companies with SMRs under development to meet the growing needs of AI data centers...

One energy analyst does not expect nuclear SMRs to be operational until 2030, yet he and many others acknowledge the need for sustainable, carbon-free alternatives to electricity, wind, and solar is very pressing. "Today's electric grids are struggling to keep up with demand, even as datacenter companies are planning huge new additions to their fleets to power generative AI applications. As a result, companies like Google, Amazon, and Microsoft are increasingly taking matters into their own hands and getting creative. They are now looking at on-site nuclear-based SMRs, and even fusion reactors," says Peter Kelly-Detwiler, principal of Northbridge Energy Partners. "This global arms race for power arose pretty quickly, and it's like nothing we have ever seen before."

America's Department of Energy has three R&D labs, according to Wikipedia, one of which is Sandia National Labs. And that New Mexico-based lab has just announced that "A milestone in quantum sensing is drawing closer, promising exquisitely accurate, GPS-free navigation." with research into "a motion sensor so precise it could minimize the nation's reliance on global positioning satellites." Until recently, such a sensor — a thousand times more sensitive than today's navigation-grade devices — would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology. For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable. The team published its findings and introduced a new high-performance silicon photonic modulator — a device that controls light on a microchip — as the cover story in the journal Science Advances... The new modulator is the centerpiece of a laser system on a microchip. Rugged enough to handle heavy vibrations, it would replace a conventional laser system typically the size of a refrigerator...

Besides size, cost has been a major obstacle to deploying quantum navigation devices. Every atom interferometer needs a laser system, and laser systems need modulators. "Just one full-size single-sideband modulator, a commercially available one, is more than $10,000," said Sandia scientist Jongmin Lee. Miniaturizing bulky, expensive components into silicon photonic chips helps drive down these costs. "We can make hundreds of modulators on a single 8-inch wafer and even more on a 12-inch wafer," Kodigala said. And since they can be manufactured using the same process as virtually all computer chips, "This sophisticated four-channel component, including additional custom features, can be mass-produced at a much lower cost compared to today's commercial alternatives, enabling the production of quantum inertial measurement units at a reduced cost," Lee said.

As the technology gets closer to field deployment, the team is exploring other uses beyond navigation. Researchers are investigating whether it could help locate underground cavities and resources by detecting the tiny changes these make to Earth's gravitational force. They also see potential for the optical components they invented, including the modulator, in LIDAR, quantum computing, and optical communications.
