A breakthrough in quantum research – the first detection of excitons (electrically neutral quasiparticles) in a topological insulator has been achieved by an international team of scientists collaborating within the Würzburg-Dresden Cluster of Excellence ct.qmat. This discovery paves the way for a new generation of light-driven computer chips and quantum technologies. It was enabled thanks to smart material design in Würzburg, the birthplace of topological insulators. The findings have been published in the journal Nature Communications.

<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio. It covers the natural sciences, including physics, biology, chemistry, medicine, and earth sciences. It began publishing in 2010 and has editorial offices in London, Berlin, New York City, and Shanghai.

One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics showed that electrons live a far more interesting life, meandering around the nucleus in clouds that look like tiny balloons. These balloons are known as atomic orbitals, and they come in all sorts of different shapes—perfectly round, two-lobed, clover-leaf-shaped. The number of lobes in the balloon signifies how much the electron spins about the nucleus.

That’s all well and good for individual atoms, but when atoms come together to form something solid—like a chunk of metal, say—the outermost electrons in the atoms can link arms and lose sight of the nucleus from where they came, forming many oversized balloons that span the whole chunk of metal. They stop spinning about their nuclei and flow through the metal to carry electrical currents, shedding the diversity of multi-lobed balloons.

Now, researchers at the Quantum Materials Center (QMC) at the University of Maryland (UMD), in collaboration with theorists at the Condensed Matter Theory Center (CMTC) and Joint Quantum Institute (JQI), have produced the first experimental evidence that one metal—and likely others in its class—have electrons that manage to preserve a more interesting, multi-lobed structure as they move around in a solid. The team experimentally studied the shape of these balloons and found not a uniform surface, but a complex structure. This unusual metal is not only fundamentally interesting, but it could also prove useful for building quantum computers that are resistant to noise.

Google has warned that growth in the use of Android in India may stall due to an antitrust order issued by the Indian antitrust watchdog last year over the U.S. company’s domination in the country.

The order, which was issued by the Competition Commission of India (CCI) in September, found that Google had abused its dominant position in the market for mobile operating systems by imposing restrictive contracts on mobile manufacturers.

The CCI ordered Google to change its contracts with manufacturers, allowing them more freedom to install rival apps and services on Android devices. According to a Reuters report, Google filed a challenge with India’s Supreme Court and said that the order would require some modifications of its existing contracts and new license agreements. It would alter the company’s existing arrangements with over 1,100 device manufacturers and thousands of app developers.

Apple will apparently start with a chip that replaces the Wi-Fi and Bluetooth chip it already uses from Broadcom, but down the line, it might make a chip that includes cellular functionality, too.

Apple is working on a new in-house chip that would power cellular, Wi-Fi, and Bluetooth functionality on its devices, according to a report from Bloomberg.

Bloomberg also shared some new information about Apple’s efforts to develop its own cellular modems to replace Qualcomm’s.

That general question is still hard to answer, again in part because of those pesky errors. (Future quantum machines will compensate for their imperfections using a technique called quantum error correction, but that capability is still a ways off.) Is it possible to get the hoped-for runaway quantum advantage even with uncorrected errors?

Most researchers suspected the answer was no, but they couldn’t prove it for all cases. Now, in a paper posted to the preprint server arxiv.org, a team of computer scientists has taken a major step toward a comprehensive proof that error correction is necessary for a lasting quantum advantage in random circuit sampling — the bespoke problem that Google used to show quantum supremacy. They did so by developing a classical algorithm that can simulate random circuit sampling experiments when errors are present.

Ralph Lydic, professor in the UT Department of Psychology, and Dmitry Bolmatov, a research assistant professor in the UT Department of Physics and Astronomy, are part of a UT/ORNL research team studying how bio-inspired materials might inform the design of next-generation computers. Their results, published recently in the Proceedings of the National Academy of Sciences, could have big implications for both edge computing and human health.

Scientists at ORNL and UT discovered an artificial cell membrane is capable of long-term potentiation, or LTP, a hallmark of biological learning and memory. This is the first evidence that a cell membrane alone—without proteins or other biomolecules embedded within it—is capable of LTP that persists for many hours. It is also the first identified nanoscale structure in which memory can be encoded.

“When facilities were shut down as a result of COVID, this led us to pivot away from our usual membrane research,” said John Katsaras, a biophysicist in ORNL’s Neutron Sciences Directorate specializing in neutron scattering and the study of biological membranes at ORNL. “Together with postdoc Haden Scott, we decided to revisit a system previously studied by Pat Collier and co-workers, this time with an entirely different electrical stimulation protocol that we termed ‘training.’”.

Google announced a new HD version of its Maps service for cars with the Android Automotive operating system. The new HD maps will provide more detailed road markings, lane-level localization, road barriers and signs. The feature will debut on the Volvo EX90 and Polestar 3 models and will benefit from the lidar, radar and camera sensors on vehicles to ensure a safer driving experience.
