Researchers at the University of California, Irvine and Los Alamos National Laboratory, publishing in the latest issue of Nature Communications, describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.

“The materials we made are substances that exhibit unique electrical or quantum properties because of their specific atomic shapes or structures,” said Luis A. Jauregui, professor of physics & astronomy at UCI and lead author of the new paper. “Imagine if we could transform glass, typically considered an insulating material, and convert it into efficient conductors akin to copper. That’s what we’ve done.”

Conventional computers use silicon as a conductor, but silicon has limits. Quantum computers stand to help bypass these limits, and methods like those described in the new study will help quantum computers become an everyday reality.

Apple’s latest gadget, the Apple Vision Pro, is a mixed-reality headset that promises to immerse users in a new dimension of spatial computing. But what makes this device so special, and how does it work?

To find out, the folks at iFixit did what they do best: they took it apart. In their usual fashion, they documented the process in a video and an article, giving us a glimpse of the inner workings of Apple’s most advanced hardware ever.

Apple has always been known for its innovative products, but its latest creation might be its most ambitious. The Apple Vision Pro is a headset that promises to revolutionize how we interact with technology by seamlessly blending the digital and physical worlds.

The device, which costs a whopping $3,500, has already hit the stores and attracted much attention. Some people are eager to try out the new possibilities of spatial computing, while others are mocking the sight of people wearing the bulky and futuristic-looking gadget.

One of the first to test the Apple Vision Pro in the real world was Casey Neistat, a popular social media personality and filmmaker. In a video posted on Saturday, he showed how he used the device in its passthrough mode, allowing him to see his surroundings through cameras and screens while accessing various virtual features.

Scientists outline new processes for leveraging hafnia’s ferroelectric features with the aim of enhancing high-performance computing.

Scientists and engineers have been pushing for the past decade to leverage an elusive ferroelectric material called hafnium oxide, or hafnia, to usher in the next generation of computing memory. A team of researchers including the University of Rochester’s Sobhit Singh published a Proceedings of the National Academy of Sciences study outlining progress toward making bulk ferroelectric and antiferroelectric hafnia available for use in a variety of applications.

In a specific crystal phase, hafnia exhibits ferroelectric properties—that is, electric polarization that can be changed in one direction or another by applying an external electric field. This feature can be harnessed in data storage technology. When used in computing, ferroelectric memory has the benefit of non-volatility, meaning it retains its values even when powered off, one of several advantages over most types of memory used today.

The company’s X3D chips will arrive later in the year, right before Intel launches Arrow Lake.

The mega tech company’s ambition is to operate on carbon-free energy by 2030.

In its most substantial offshore wind project deal to date, Google has signed power purchase agreements (PPAs) for over 700 megawatts of clean energy to power its European data centers.

The company’s announcement is in line with its ambitious goal to achieve net-zero emissions across all of its operations and value chain by 2030, as per Google’s Environmental Report published last year.

New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies.

As demands for computing resources continue to increase rapidly, scientists and engineers are looking for ways to build faster systems for processing information. One possible solution is to use patterns of electron spins, called spin waves, to transfer and process information much more rapidly than in conventional computers. So far, a major challenge has been in manipulating these ultrafast spin waves to do useful work.

Breakthrough in Spin Wave Manipulation.

A New approach goes beyond spin to find 20x as long coherence times.

Yesterday saw the first round of hands-on and unboxing videos for Apple Vision Pro, sharing some interesting tidbits about Apple’s first spatial computer. After an initial unboxing video yesterday, MKBHD has now shared an in-depth look at what it’s like to actually use Apple Vision Pro.

Here are a few random tidbits taken from various Vision Pro reviews and videos so far.
