“Until now researchers have encoded and stabilized. We now show that we can compute as well.”

Researchers at QuTech—a collaboration between the TU Delft and TNO—have reached a milestone in quantum error correction. They have integrated high-fidelity operations on encoded quantum data with a scalable scheme for repeated data stabilization. The researchers report their findings in the December issue of Nature Physics.

Physical quantum bits, or qubits, are vulnerable to errors. These errors arise from various sources, including quantum decoherence, crosstalk, and imperfect calibration. Fortunately, the theory of quantum error correction stipulates the possibility to compute while synchronously protecting quantum data from such errors.

During NeurIPS 2021, seven quantum computer scientists from Amazon came together to discuss the current state of quantum computing, some of the biggest challenges facing the field, and what the future might hold.

Panelists included:
• Simone Severini, director of quantum computing.
• Antia Lamas-Linares, principal research scientist.
• Earl Campbell, senior research scientist.
• John Preskill, Amazon Scholar.
• Katharine Hyatt, applied scientist.
• James Whitfield, Amazon Visiting Academic.
• Helmut Katzgraber, senior practice manager.

The company’s current Glass hardware is built on Android.

Google is hiring an “Augmented Reality OS” team focused on building software for an “innovative AR device,” according to job listings spotted by 9to5Google. The team is led by Mark Lucovsky, who announced he’d joined the company this week. Lucovsky previously worked at Meta developing an in-house alternative to Android to power the company’s hardware, and also co-authored the Windows NT operating system.

According to Google’s job listings, the Augmented Reality OS team is building “the software components that control and manage the hardware on [its] Augmented Reality (AR) products.” This is far from Google’s first stab at developing AR software, and follows the company’s work on ARCore for Android and Tango. The company’s Google Glass, which is aimed at the business and enterprise market, is currently built on Android.

“We will constantly be ‘within’ the internet, rather than have access to it, and within the billions of interconnected computers around us,” Ball wrote in his Metaverse Primer. Mark Zuckerberg described the metaverse similarly, calling it “an even more immersive and embodied internet.” Picture this: you strap on a headset or pair of goggles, flick a switch, and boom—you’re still standing in your living room, but you’re also walking through a 3D world as an avatar of yourself, and you can interact with other people who are doing the same thing from their living rooms.

Being constantly within the internet doesn’t sound all that appealing to me personally—in fact, it sounds pretty terrible—but the good news for those with a similar sentiment is that the “full vision” of the metaverse, according to Ball, is still decades away, primarily because of the advances in computing power, networking, and hardware necessary to enable and support it.

Albert Einstein and Stephen Hawking – the most famous physicists of the twentieth century — both spent decades trying to find a single law that could explain how the world works on the scale of the atom and on the scale of galaxies. In short, the Standard Model describes the physics of the very small. General relativity describes the physics of the very large. The problem? The two theories tell different stories about the fundamental nature of reality. Einstein described the problem nearly a century ago in his 1923 Nobel lecture 0, telling the audience that a physicist who searches for, “an integrated theory cannot rest content with the assumption that there exist two distinct fields totally independent of each other by their nature.” Even while on his deathbed, Einstein worked on a way to unite all the laws of physics under one unifying theory.

Yet despite the chip giant’s manufacturing struggles, it still maintains nearly 90% market share in data-center chips, compared with AMD’s 10%, according to data from Mercury Research. Intel has lost more ground in desktop and laptop computers, holding onto 83% market share and 78% share respectively, with the remainder going mostly to AMD, according to Mercury data.

After years of hearing about these problems, Wall Street had largely written off the company’s manufacturing prowess. Investors expected the company to move to a hybrid approach to chip making, contracting more of its chip manufacturing to TSMC and potentially to Samsung. Some analysts suggested the company go as far as spinning out the manufacturing business, as AMD did with what is now known as GlobalFoundries years ago.

But weeks after Gelsinger took over, he announced that the company planned to double down on its manufacturing business in an effort to return Intel to its roots, including a bid to compete with TSMC as a contract manufacturer. Since his return to Intel after nearly nine years as chief executive of VMware, he has shaken up the company’s executive team. That includes re-hiring several notable Intel staffers, including Natarajan.

The mathematician Ben Green of the University of Oxford has made a major stride toward understanding a nearly 100-year-old combinatorics problem, showing that a well-known recent conjecture is “not only wrong but spectacularly wrong,” as Andrew Granville of the University of Montreal put it. The new paper shows how to create much longer disordered strings of colored beads than mathematicians had thought possible, extending a line of work from the 1940s that has found applications in many areas of computer science.

The conjecture, formulated about 17 years ago by Ron Graham, one of the leading discrete mathematicians of the past half-century, concerns how many red and blue beads you can string together without creating any long sequences of evenly spaced beads of a single color. (You get to decide what “long” means for each color.)

This problem is one of the oldest in Ramsey theory, which asks how large various mathematical objects can grow before pockets of order must emerge. The bead-stringing question is easy to state but deceptively difficult: For long strings there are just too many bead arrangements to try one by one.

When Patch Tuesday rolls around, we can usually expect a series of Windows problems to be fixed (and perhaps to see some new ones introduced), as well as new features added. But Microsoft also uses such updates to take things away — and this is precisely what has happened with the latest updates for Windows 10 and 11.

Microsoft, quite understandably, would like everyone to use its Edge browser, and has taken endless steps to ensure that it stays the default browser on as many computers as possible. With the latest operating system updates — specifically the KB5008212 and KB5008215 updates — the company has implemented a block on workarounds used by the likes of EdgeDeflector and Firefox to force links to open in a browser other than Edge.

And he’s been searching for it for a decade.

It’s a nightmare scenario that might become increasingly common in a world of digital currency. A man threw away an old PC hard drive while doing a quick spring clean of his home in Newport Wales, U.K., in 2013. Fast-forward almost a decade and he’s still desperately petitioning to be allowed to go through his local landfill.

The reason the man, 35-year-old IT engineer James Howells, wants to trawl through his local trash site is that the hard drive he threw out included a wallet with 7,500 Bitcoin.
