An anonymous reader quotes a report from Ars Technica: On Tuesday, the quantum computing startup Quera laid out a road map that will bring error correction to quantum computing in only two years and enable useful computations using it by 2026, years ahead of when IBM plans to offer the equivalent. Normally, this sort of thing should be dismissed as hype. Except the company is Quera, which is a spinoff of the Harvard University lab that demonstrated the ability to identify and manage errors using hardware that's similar in design to what Quera is building. Also notable: Quera uses the same type of qubit that a rival startup, Atom Computing, has already scaled up to over 1,000 qubits. So, while the announcement should be viewed cautiously -- several companies have promised rapid scaling and then failed to deliver -- there are some reasons it should be viewed seriously as well. [...]

As our earlier coverage described, the Harvard lab where the technology behind Quera's hardware was developed has already demonstrated a key step toward error correction. It created logical qubits from small collections of atoms, performed operations on them, and determined when errors occurred (those errors were not corrected in these experiments). But that work relied on operations that are relatively easy to perform with trapped atoms: two qubits were superimposed, and both were exposed to the same combination of laser lights, essentially performing the same manipulation on both simultaneously. Unfortunately, only a subset of the operations that are likely to be desired for a calculation can be done that way. So, the road map includes a demonstration of additional types of operations in 2024 and 2025. At the same time, the company plans to rapidly scale the number of qubits. Its goal for 2024 hasn't been settled on yet, but [Quera's Yuval Boger] indicated that the goal is unlikely to be much more than double the current 256. By 2025, however, the road map calls for over 3,000 qubits and over 10,000 a year later. This year's small step will add pressure to the need for progress in the ensuing years.

If things go according to plan, the 3,000-plus qubits of 2025 can be combined to produce 30 logical qubits, meaning about 100 physical qubits per logical one. This allows fairly robust error correction schemes and has undoubtedly been influenced by Quera's understanding of the error rate of its current atomic qubits. That's not enough to perform any algorithms that can't be simulated on today's hardware, but it would be more than sufficient to allow people to get experience with developing software using the technology. (The company will also release a logical qubit simulator to help here.) Quera will undoubtedly use this system to develop its error correction process -- Boger indicated that the company expected it would be transparent to the user. In other words, people running operations on Quera's hardware can submit jobs knowing that, while they're running, the system will be handling the error correction for them. Finally, the 2026 machine will enable up to 100 logical qubits, which is expected to be sufficient to perform useful calculations, such as the simulation of small molecules. More general-purpose quantum computing will need to wait for higher qubit counts still.

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission is about to start winding down a program that gives $30 monthly broadband discounts to people with low incomes, and says it will have to complete the shutdown by May if Congress doesn't provide more funding. The 2-year-old Affordable Connectivity Program (ACP) was created by Congress, and Democrats have been pushing for more funding to keep it going. But Republican members of Congress blasted the ACP last month, accusing the FCC of being "wasteful."

In a letter, GOP lawmakers complained that most of the households receiving the subsidy already had broadband service before the program existed. They threatened to withhold funding and criticized what they called the "Biden administration's reckless spending spree." The letter was sent by the highest-ranking Republicans on committees with oversight responsibility over the ACP, namely Sen. John Thune (R-SD), Sen. Ted Cruz (R-Texas), Rep. Cathy McMorris Rodgers (R-Wash.), and Rep. Bob Latta (R-Ohio). With no resolution in sight, the FCC announced that it would have to start sending out notices about the program's expected demise. "With less than four months before the projected program end date and without any immediate additional funding, this week the Commission expects to begin taking steps to start winding down the program to give households, providers, and other stakeholders sufficient time to prepare," the FCC said in an announcement yesterday.

The Biden administration has requested $6 billion to fund the program through December 2024. As of now, the FCC said it "expects funding to last through April 2024, running out completely in May." FCC Chairwoman Jessica Rosenworcel has repeatedly asked Congress for more ACP funding, and sent a letter (PDF) to lawmakers yesterday in which she repeated her plea. The chairwoman's letter said that 23 million households are enrolled in the discount program. [...] Rosenworcel warned that the impending ACP shutoff "would undermine the historic $42.5 billion Broadband Equity, Access, and Deployment Program," a different program created by Congress to subsidize ISPs' expansion of broadband networks throughout the US. The discount and deployment programs complement each other because "the ACP supports a stable customer base to help incentivize deployment in rural areas," Rosenworcel wrote.

Alphabet's Google is set to go before a federal jury in Boston on Tuesday in a trial over accusations that processors it uses to power AI technology in key products infringe a computer scientist's patents. From a report: Singular Computing, founded by Massachusetts-based computer scientist Joseph Bates, claims Google copied his technology and used it to support AI features in Google Search, Gmail, Google Translate and other Google services. A Google court filing said that Singular has requested up to $7 billion in monetary damages, which would be more than double the largest-ever patent infringement award in U.S. history.

Google spokesperson Jose Castaneda called Singular's patents "dubious" and said that Google developed its processors "independently over many years." "We look forward to setting the record straight in court," Castaneda said.

With Apple's Vision Pro VR/AR headset set to go on sale on February 2, we're starting to see more details about the app requirements. From a report: The company has released guidelines for visionOS developers planning to release apps and there's one strange caveat. It would rather developers don't use the terms AR and VR when referring to Vision Pro apps, but rather call them "spatial computing apps," according to the developer page.

"Spatial computing: Refer to your app as a spatial computing app. Don't describe your app experience as augmented reality (AR), virtual reality (VR), extended reality (XR), or mixed reality (MR)," the company states. The headset itself should be called "Apple Vision Pro" with three uppercase words, while "visionOS begins with a lowercase v, even when it's the first word in a sentence." The terms should never be translated or transliterated, Apple added.

home-electro.com shares a report from Engadget: On Sunday night Samsung held its annual First Look event at CES 2024, where the company teased the world's first transparent MicroLED display. While there's still no word on how much it costs or when this tech will find its way into retail devices, Samsung showcased its transparent MicroLED display side-by-side next to transparent OLED and transparent LCD models to really highlight the differences between the tech. Compared to the others, not only was the MicroLED panel significantly brighter, it also featured a completely frameless design and a more transparent glass panel that made it easier to see objects behind it. LG also unveiled a similar piece of tech: the company's "first wireless transparent OLED TV." It's called the OLED T and supports 4K resolution and LG's wireless transmission tech for audio and video.
