Posted by in categories: computing, quantum physics

This Review examines the scaling prospects of quantum computing systems based on silicon spin technology and how the different layers of such a computer could benefit from using complementary metal–oxide–semiconductor (CMOS) technology.

Engineers produce the world’s longest flexible fiber battery

Posted by in categories: computing, sustainability, wearables

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape.

The researchers envision new possibilities for self-powered communications, sensing, and computational devices that could be worn like ordinary clothing, as well as devices whose batteries could also double as structural parts.

In a proof of concept, the team behind the new battery technology has produced the world’s longest flexible fiber battery, 140 meters long, to demonstrate that the material can be manufactured to arbitrarily long lengths. The work is described today in the journal Materials Today. MIT postdoc Tural Khudiyev (now an assistant professor at National University of Singapore), former MIT postdoc Jung Tae Lee (now a professor at Kyung Hee University), and Benjamin Grena SM ‘13, Ph.D. ‘17 (currently at Apple) are the lead authors on the paper. Other co-authors are MIT professors Yoel Fink, Ju Li, and John Joannopoulos, and seven others at MIT and elsewhere.

New semiconductor design could extend Moore’s Law

Posted by in categories: business, computing

“Today’s technology announcement is about challenging convention and rethinking how we continue to advance society and deliver new innovations that improve life, business and reduce our environmental impact,” said Dr. Mukesh Khare, Vice President of Hybrid Cloud and Systems, IBM Research. “Given the constraints the industry is currently facing along multiple fronts, IBM and Samsung are demonstrating our commitment to joint innovation in semiconductor design and a shared pursuit of what we call ‘hard tech.’”

Moore’s Law – an ongoing trend that shows the number of transistors on a computer chip doubling every two years or so – is now approaching what are considered fundamental barriers. Simply put, as more and more transistors are crammed into a finite area, engineers are running out of space.

Historically, transistors have been built to lie flat upon the surface of a semiconductor, with the electric current flowing laterally, or side-to-side, through them. Vertical Transport Field Effect Transistors (VTFET), by contrast, are built perpendicular to the surface of the chip with a vertical, or up-and-down, current flow.

Samsung and IBM developing battery tech that could give us weeklong batteries

Posted by in categories: computing, mobile phones

That could change though, because Samsung and IBM have announced a partnership in which both companies are working together to develop new battery tech that could allow our smartphones to run for an entire week on a single charge.

This comes in the form of a new chip architecture that could potentially reduce the amount of energy consumed by as much as 85% called Vertical-Transport Nanosheet Field Effect Transistor (VTFET). As the name suggests, this new design will allow signals to travel across the chip vertically by stacking transistors on top of each other.

As a result, this could allow phones to perform just as well as they do right now, but with massive gains in energy efficiency. Alternatively, this design would also allow phones to improve on its performance by as much as 100% compared to modern FET alternatives.

LG announce their first gaming laptop, the LG UltraGear 17G90Q

Posted by in categories: computing, entertainment

LG Electronics USA has just announced its first gaming laptop, the LG UltraGear 17G90Q.

The LG UltraGear 17G90Q is powered by an 11th Gen Intel® Tiger Lake H processor, NVIDIA GeForceTM RTX 3,080 Max-Q graphics card, dual-channel memory and an ultra-fast dual SSD setup. In addition to a 17-inch IPS panel with a 1 millisecond response time and a 300Hz refresh rate, the LG UltraGear gaming laptop ensures immersive, fluid gameplay. To stop all this high-end hardware from melting, the LG 17G90Q cooling system features a vapor chamber that keeps the laptop running cool, even when pushed to the limits.

Important Milestone Reached in Quantum Computing With Error Correction

Posted by in categories: computing, quantum physics

“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.

Google staffs up to build OS for unknown ‘innovative AR device’

Posted by in categories: augmented reality, business, computing, mobile phones

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.

The Metaverse Will Need 1,000x More Computing Power, Says Intel

Posted by in categories: computing, mobile phones

“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.

The Universe Might Be a Self-Learning Computer. Here’s What That Means

Posted by in categories: computing, particle physics, space

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.
