Amazon has introduced its first-ever quantum processor, dubbed Ocelot, designed specifically to reduce quantum error correction costs by up to 90% compared to existing approaches. The prototype chip uses "cat qubits" -- named after Schrodinger's cat thought experiment -- which intrinsically suppress certain types of quantum errors.

Unlike conventional approaches that add error correction after designing the architecture, AWS built Ocelot with quantum error correction as the primary requirement. The chip consists of two stacked 1cm2 silicon microchips containing 14 core components: five data qubits, five buffer circuits for stabilization, and four qubits dedicated to error detection.

Quantum computers are notoriously sensitive to environmental noise -- including vibrations, heat, and electromagnetic interference -- which disturbs qubits and generates computational errors. These errors multiply as quantum systems scale up, creating a significant barrier to practical quantum computing. Ocelot's high-quality oscillators, made from a thin film of superconducting Tantalum processed using specialized techniques developed by AWS material scientists, generate the repetitive electrical signals that maintain quantum states.

"We're just getting started and we believe we have several more stages of scaling to go through," said Oskar Painter, AWS director of Quantum Hardware, whose team published their findings in Nature. Industry analyst Heather West of IDC was more measured, categorizing Ocelot as "much more of an advancement and less of a breakthrough," noting that superconducting qubits designed to resist certain error types aren't completely novel.

Lucid CEO Peter Rawlinson has stepped down, with COO Marc Winterhoff taking over as interim CEO. The company also announced its fourth-quarter financial results and revealed plans to more than double vehicle production to 20,000 units in 2025. CNBC reports: Winterhoff told CNBC on Tuesday that it was Rawlinson's decision to resign as of Friday, however he declined to elaborate on any additional details. "It was Peter's decision after 12 years of, let's say, daily grind or daily activities and bringing the company where it is today ... that it is time to step aside and pass the baton," said Winterhoff, who joined Lucid from Roland Berger in December 2023. In a statement posted Tuesday on LinkedIn, Rawlinson said he decided it was "finally the right time" to step down after "successfully" launching the company's second product, a three-row SUV called the Gravity. He did not elaborate further on the decision in the lengthy post.

The CEO change and production target were announced in conjunction with the automaker's fourth-quarter financial results. For the period ended Dec. 31, the company reported a net loss attributable to common stockholders of $636.9 million, or a loss of 22 cents per share, on revenue of $234.5 million. Analysts surveyed by LSEG expected a loss of 25 cents per share on revenue of $214 million. During the same period last year, Lucid reported a net loss attributable to common stockholders of $653.8 million, or a loss of 29 cents per share, on revenue of $157.2 million. The production target for 2025 announced Tuesday is compared with production of 9,029 vehicles and deliveries of 10,241 reported for 2024. Winterhoff said production of the Gravity SUV will gradually build during the year. He declined to speculate on what percentage of the 20,000-unit production target the vehicle would represent.

An anonymous reader quotes a report from Ars Technica: Following up on Microsoft's announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two different types of qubit hardware to improve the stability of the quantum information they hold. The idea is that one type of qubit is resistant to errors, while the second can be used for implementing an error-correction code that catches the problems that do happen. While there have been more effective demonstrations of error correction in the past, a number of companies are betting that Amazon's general approach is the best route to getting logical qubits that are capable of complex algorithms. So, in that sense, it's an important proof of principle. Amazon's quantum computing approach combines cat qubits for data storage and transmons for error correction.

Cat qubits are quantum bits that distribute their superposition state across multiple photons in a resonator, making them highly resistant to bit flip errors. Transmons are superconducting qubits that help detect and correct phase flip errors by enabling weak measurements without destroying the quantum state. Meanwhile, a phase flip is a quantum error that alters the relative phase of a qubit's superposition state without changing its probability distribution. Unlike a bit flip, which swaps a qubit's state probabilities, a phase flip changes how the quantum states interfere, potentially disrupting quantum computations.

By alternating cat qubits with transmons, Amazon reduces the number of hardware qubits needed for error correction. Their tests show that increasing qubits lowers the error rate, proving the system's effectiveness. However, rare bit flips still cause entire logical qubits to fail, and transmons remain prone to both bit and phase flips. If you're still entangled in this story without decohering into pure quantum chaos, kudos to you!

Google has updated its Results About You tool with a redesigned hub, easier removal requests directly from Search, and the ability to refresh outdated results. Engadget reports: Today, the tech giant is announcing the latest changes, including a redesigned hub and the ability to update outdated search results to reflect the latest changes.

The redesign isn't only for show. You can now submit removal requests directly from Search with fewer actions by clicking or tapping the three dots beside a search result. If you manage to have content about you deleted or changed from a website but Google Search hasn't caught up, you can refresh the search, which will "recrawl the page and obtain the latest information." In other words, you can always see the most up-to-date results about you.

Cellebrite says it has stopped Serbia from using its technology following allegations that Serbian police and intelligence used Cellebrite's technology to unlock the phones of a journalist and an activist, and then plant spyware. From a report: In December 2024, Amnesty International published a report that accused Serbian police of using Cellebrite's forensics tools to hack into the cellphones of a local journalist and an activist. Once their phones were unlocked, Serbian authorities then installed an Android spyware, which Amnesty called Novispy, to keep surveilling the two.

In a statement, Cellebrite said that "after a review of the allegations brought forth by the December 2024 Amnesty International report, Cellebrite took precise steps to investigate each claim in accordance with our ethics and integrity policies. We found it appropriate to stop the use of our products by the relevant customers at this time."

An anonymous reader quotes a report from 9to5Google: Starting with the Snapdragon 8 Elite, Qualcomm will offer device manufacturers (OEMs) the "ability to provide support for up to eight consecutive years of Android software and security updates." Qualcomm today announced a "program" in partnership with Google: "What this means is that support for platform software included in this program will be made available to OEMs for eight consecutive years, including both Android OS and kernel upgrades, without requiring significant changes or upgrades to the platform and OEM code on the device (a separation commonly referred as 'Project Treble' or the 'vendor implementation'). While kernel changes will require updating kernel mode drivers, the vendor code can remain unchanged while the software support is being provided."

This program specifically includes "two upgrades to the mobile platform's Android Common Kernel (ACK) to support the eight-year window." It's ultimately up to manufacturers to update their devices, but the bottleneck going forward won't be the chip. Qualcomm today notes how the extended software support it's providing can "lower costs for OEMs interested in supporting their devices longer." The first devices to benefit are Snapdragon 8 Elite-powered smartphones launching with Android 15. Notably, the program runs for the "next five generations" of SoCs, including Snapdragon 8 and 7-series chips launching "later this year." Older chipsets will not benefit from this program.

Our World in Data: To decarbonize road transport, the world must move away from petrol and diesel cars and towards electric vehicles and other forms of low-carbon transport.

This transition has already started. In fact, global sales of combustion engine cars are well past the peak and are now falling.

As you can see in the chart, global sales peaked in 2018. This is calculated based on data from the International Energy Agency. Bloomberg New Energy Finance estimates this peak occurred one year earlier, in 2017.

Sales of electric cars, on the other hand, are growing quickly.

A New York law mandating low-cost broadband is inspiring similar legislation across multiple states, despite industry opposition. The law requires ISPs with over 20,000 customers to offer $15 plans with 25Mbps speeds or $20 plans with 200Mbps to income-eligible residents.

Vermont, Massachusetts, and California legislators have introduced comparable bills following New York's success. Vermont's proposal mirrors New York's pricing structure, while Massachusetts goes further by requiring 100Mbps speeds for the $15 tier. AT&T responded by withdrawing its 5G home internet service from New York rather than complying with the mandate.

Industry lobby groups continue fighting these regulations, with USTelecom warning that state-level price controls will "undermine connectivity progress" and "discourage investment."

Google has launched a free version of Gemini Code Assist, offering developers substantially higher usage limits than competing services. From a report: The AI coding assistant, powered by the fine-tuned Gemini 2.0 model, allows up to 180,000 code completions monthly -- 90 times more than GitHub Copilot's free tier limit of 2,000. The release comes just one day after Anthropic introduced Claude Code, underscoring intensifying competition in AI-powered development tools.

Gemini Code Assist integrates with popular environments including Visual Studio Code, JetBrains IDEs, and GitHub, where it performs code reviews on both public and private repositories. Google's offering features a 128,000-token context window, enabling developers to work with larger codebases. The service supports all public domain programming languages and requires only a Gmail account to register, with no credit card needed.

According to Ryan Salva, Google Cloud's senior director of product management, more than 75% of developers now rely on AI in their daily work, with over 25% of new code at Google being AI-generated. For developers wanting advanced features like private repository integration or Google Cloud service connections, premium tiers remain available.

Online-education company Chegg said it is conducting a business review and exploring alternatives such as selling the company or taking it private as it continues to lose subscribers to artificial-intelligence-enabled rivals. From a report: Chegg and other virtual-learning companies have ceded ground to generative-AI companies such as ChatGPT, which provides free alternatives to the homework help that Chegg charges $19.95 for to its subscribers. Although Chegg built its own AI products, the company has faced scores of canceled subscriptions. The business review comes as the company swung to a loss in the fourth quarter, with revenue falling 24%, and guided for lower-than-expected revenue for the first quarter. In November, Chegg said it would cut its workforce by an additional 21%. Chegg's shares have fallen 99% since its peak in 2021.

An anonymous reader quotes a report from TorrentFreak: In France, rightsholders have taken legal action to compel large VPN providers to support their pirate site blocking program. The aim is to reinforce existing blocking measures, but VPN providers see this as a dangerous move, leading to potential security issues and overblocking. As a result, some are considering leaving France altogether if push comes to shove. [...] Earlier this month, sports rightsholders Canal+ and LFP requested blocking injunctions that would require popular VPNs to start blocking pirate sites and services. The full requests are not public, but the details available show that Cyberghost, ExpressVPN, NordVPN, ProtonVPN, and Surfshark are listed as respondents. [...]

The blocking request has yet to be approved and several of the targeted VPN providers have reserved detailed commentary, for now. That said, the VPN Trust Initiative (VTI), which includes ExpressVPN, NordVPN and Surfshark as members, has been vocal in its opposition. VTI is part of the i2Coalition and while it doesn't speak directly for any of the members, the coalition's Executive Director Christian Dawson has been in regular discussions with VPN providers. From this, it became clear that VPN providers face difficult decisions. If VPN providers are ordered to block pirate sites, some are considering whether to follow in the footsteps of Cisco, which discontinued its OpenDNS service in the country, to avoid meddling with its DNS resolver.

Speaking with TorrentFreak, VTI's Dawson says that VPNs have previously left markets like India and Pakistan in response to restrictive requirements. This typically happens when privacy or security principles are at risk, or if the technical implementation of blocking measures is infeasible. VTI does not rule out that some members may choose to exit France for similar reasons, if required to comply with blocking measures. "We've seen this before in markets like India and Pakistan, where regulatory requirements forced some VPN services to withdraw rather than compromise on encryption standards or log-keeping policies," Dawson says. "France's potential move to force VPN providers to block content could put companies in a similar position -- where they either comply with measures that contradict their purpose or leave the market altogether." "This case in France is part of a broader global trend of regulatory overreach, where governments attempt to control encrypted services under the guise of content regulation. We've already seen how China, Russia, Myanmar, and Iran have imposed VPN restrictions as part of broader censorship efforts."

"The best path forward is for policymakers to focus on targeted enforcement measures that don't undermine Internet security or create a precedent for global Internet fragmentation," concludes Dawson. "As seen in other cases, blanket blocking measures do not effectively combat piracy but instead create far-reaching consequences that disrupt the open Internet."

Microsoft has updated its CPU compatibility list for Windows 11 24H2, excluding pre-11th-generation Intel processors for OEMs building new PCs. The Register reports: Windows 11 24H2 has been available to customers for months, yet Microsoft felt compelled in its February update to confirm that builders, specifically, must use Intel's 11th-generation or later silicon when building brand new PCs to run its most recent OS iteration. "These processors meet the design principles around security, reliability, and the minimum system requirements for Windows 11," Microsoft says.

Intel's 11th-generation chips arrived in 2020 and were discontinued last year. It would be surprising, if not unheard of, for OEMs to build machines with unsupported chips. Intel has already transitioned many pre-11th generation chips to "a legacy software support model," so Microsoft's decision to omit the chips from the OEM list is understandable. However, this could be seen as a creeping problem. Chips made earlier than that were present very recently, in the list of supported Intel processors for Windows 11 22H2 and 23H2.

This new OEM list may add to worries of some users looking at the general hardware compatibility specs for Windows 11 and wondering if the latest information means that even the slightly newer hardware in their org's fleet will soon no longer meet the requirements of Microsoft's flagship operating system. It's a good question, and the answer -- currently -- appears to be that those "old" CPUs are still suitable. Microsoft has a list of hardware compatibility requirements that customers can check, and they have not changed much since the outcry when they were first published.

Chegg has filed a lawsuit against Google, accusing the tech giant of using AI-generated overviews to undermine publishers by reducing site traffic and eroding financial incentives for original content. Chegg claims this practice violates antitrust laws and threatens the integrity of the online information ecosystem. Reuters reports: This will eventually lead to a "hollowed-out information ecosystem of little use and unworthy of trust," the company said. The Santa Clara, California-based company has said Google's AI overviews have caused a drop in visitors and subscribers. Chegg was trading at around $1.63 on Monday, down more than 98% from its peak price in 2021.

The company announced it would lay off 21% of its staff in November. Nathan Schultz, CEO of Chegg, said on Monday that Google is profiting off the company's content for free. "Our lawsuit is about more than Chegg -- it's about the digital publishing industry, the future of internet search, and about students losing access to quality, step-by-step learning in favor of low-quality, unverified AI summaries," he said.

Publishers allow Google to crawl their websites to generate search results, which Google monetizes through advertising. In exchange, the publishers receive search traffic to their sites when users click on the results, Chegg said. But Google has started coercing publishers to let it use the information for AI overviews and other features that result in fewer site visitors, the company said. Chegg argued the conduct violates a law against conditioning the sale of one product on the customer selling or giving its supplier another product.

An anonymous reader quotes a report from Reuters: Cloud communications software firm Bird, one of the Netherlands' most prominent tech startups, plans to move most of its operations out of Europe, its CEO said, citing restrictive regulations and difficulties hiring skilled technology workers. "We are mostly leaving Europe as it lacks the environment we need to innovate in an AI-first era of technology," CEO Robert Vis told Reuters on Monday. "We foresee that regulations in Europe will block true innovation in a global economy moving extremely fast to AI," he said in a text message response to Reuters queries.

Bird's operations in future will be mostly split between New York, Singapore and Dubai, he said. Vis first announced the move abroad in a LinkedIn post over the weekend. Bird, formerly known as Message Bird, was founded in Amsterdam in 2011. It is a competitor of U.S.-based Twilio in the market for helping companies manage their communications with consumers across digital mediums such as messaging, email and video apps. It says it has developed an AI-powered platform that automates and streamlines business operations across entire organizations including tech leaders.

AI-powered search engine Perplexity is developing its own web browser named Comet. "Just like Perplexity reinvented search, we're also reinventing the browser," a Perplexity spokesperson told TechCrunch. "Stay tuned for updates." From the report: In a post on X on Monday, the company launched a sign-up list for the browser, which isn't yet available. It's unclear when it might be -- or what the browser will look like, even. But we do have a name: Comet. [...] Perplexity may be betting that it can leverage its search engine user base to quickly ramp up and make some sort of a dent in the space with Comet.

AT&T and Verizon have successfully completed their first cellphone-to-satellite video calls using AST SpaceMobile's satellites, marking a significant step toward commercial satellite networks. The Verge reports: Verizon has completed its first cellphone-to-satellite video call, while AT&T has completed its first using satellites that will be used as part of a commercial network. [...] Verizon pulled off "a live video call between two mobile devices with one connected via satellite and the other connected via Verizon's terrestrial network connection," according to a company press release.

In AT&T's case, "AT&T and AST SpaceMobile have successfully completed another video call by satellite to an everyday smartphone over AT&T spectrum," per AT&T's press release. Both phone companies relied on AST's constellation of five BlueBird satellites that were launched last September for the tests. AT&T's initial video call test happened in June 2023.

Microsoft has canceled some leases for US data center capacity, according to TD Cowen, raising broader concerns over whether it's securing more AI computing capacity than it needs in the long term. From a report: OpenAI's biggest backer has voided leases in the US totaling "a couple of hundred megawatts" of capacity -- the equivalent of roughly two data centers -- canceling agreements with at least a couple of private operators, the US brokerage wrote Friday, citing "channel checks" or inquiries with supply chain providers. TD Cowen said its checks also suggest Microsoft has pulled back on converting so-called statements of qualifications, agreements that usually lead to formal leases.

Microsoft in a statement on Monday reiterated its spending target for the fiscal year ending June, but declined to comment on TD Cowen's note. Exactly why Microsoft may be pulling some leases is unclear. TD Cowen posited in a second report on Monday that OpenAI is shifting workloads from Microsoft to Oracle as part of a relatively new partnership. The tech giant is also among the largest owners and operators of data centers in its own right and is spending billions of dollars on its own capacity. TD Cowen separately suggested that Microsoft may be reallocating some of that in-house investment to the US from abroad.

Financial Times: Venture capitalists have always been happy to back pre-profit companies. Back in the halcyon ZIRP era, they became happy to finance pre-revenue companies. But at least even Juicero, Wag and the Fyre Festival had an actual product. From Bloomberg over the weekend: "OpenAI co-founder Ilya Sutskever is raising more than $1 billion for his start-up at a valuation of over $30 billion, according to a person familiar with the matter -- vaulting the nascent venture into the ranks of the world's most valuable private technology companies.

Greenoaks Capital Partners, a San Francisco-based venture capital firm, is leading the deal for the start-up, Safe Superintelligence, and plans to invest $500 million, said the person, who asked not to be identified discussing private information. Greenoaks is also an investor in AI companies Scale AI and Databricks.

The round marks a significant valuation jump from the $5 billion that Sutskever's company was worth before, according to Reuters, which earlier reported some details of the new funding. The financing talks are ongoing and the details could still change."

OK, so a jump from a $5bn valuation less than half a year ago to $30bn must mean that Safe Superintelligence has an absolutely killer product right? SSI focuses on developing safe AI systems. It isn't generating revenue yet and doesn't intend to sell AI products in the near future. "This company is special in that its first product will be the safe superintelligence, and it will not do anything else up until then," Sutskever told Bloomberg in June. "It will be fully insulated from the outside pressures of having to deal with a large and complicated product and having to be stuck in a competitive rat race."

Google is preparing to abandon SMS verification codes for Gmail authentication in favor of QR codes, Gmail spokesperson Ross Richendrfer told Forbes. The move aims to address significant security vulnerabilities inherent in SMS-based verification while combating fraudulent exploitation of Google's messaging infrastructure, he said.

"Just like we want to move past passwords with the use of things like passkeys, we want to move away from sending SMS messages for authentication," Richendrfer said. The transition will target "rampant, global SMS abuse" that undermines security and enables criminal schemes. SMS verification currently serves dual purposes at Google: confirming user identity and preventing service abuse. However, these codes are vulnerable to phishing, dependent on carrier security practices, and frequently exploited in "traffic pumping" scams where fraudsters profit from artificially triggered SMS messages.

The forthcoming implementation will display QR codes that users scan with their phone cameras instead of entering six-digit codes. This approach eliminates shareable verification codes and reduces dependency on telecom carriers. The changes will roll out "over the next few months," the company said.

On Wednesday Mozilla president Mark Surman "announced plans to tackle what he says are 'major headwinds' facing the company's ability to grow, make money, and remain relevant," reports the blog OMG Ubuntu: "Mozilla's impact and survival depend on us simultaneously strengthening Firefox AND finding new sources of revenue AND manifesting our mission in fresh ways," says Surman... It will continue to invest in privacy-respecting advertising; fund, develop and push open-source AI features in order to retain 'product relevance'; and will go all-out on novel new fundraising initiatives to er, get us all to chip in and pay for it!

Mozilla is all-in on AI; Surman describes it as Mozilla's North Star for the work it will do over the next few years. I wrote about its new 'Orbit' AI add-on for Firefox recently...

Helping to co-ordinate, collaborate and come up with ways to keep the company fixed and focused on these fledgling effort is a brand new Mozilla Leadership Council.
The article argues that without Mozilla the web would be "a far poorer, much ickier, and notably less FOSS-ier place..." Or, as Mozilla's blog post put it Wednesday, "Mozilla is entering a new chapter — one where we need to both defend what is good about the web and steer the technology and business models of the AI era in a better direction.

"I believe that we have the people — indeed, we ARE the people — to do this, and that there are millions around the world ready to help us. I am driven and excited by what lies ahead."
