Charging quantum batteries in indefinite causal order. In the classical world, if you tried to charge a battery using two chargers, you would have to do so in sequence, limiting the available options to just two possible orders. However, leveraging the novel quantum effect called ICO opens the possibility to charge quantum batteries in a distinctively unconventional way. Here, multiple chargers arranged in different orders can exist simultaneously, forming a quantum superposition. ©2023 Chen et al. CC-BY-ND

Batteries that exploit quantum phenomena to gain, distribute and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power applications. For the first time, researchers including those from the University of Tokyo take advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the performance of so-called quantum batteries, bringing this future technology a little closer to reality.

When you hear the word “quantum,” the physics governing the subatomic world, developments in quantum computers tend to steal the headlines, but there are other upcoming quantum technologies worth paying attention to. One such item is the quantum battery which, though initially puzzling in name, holds unexplored potential for sustainable energy solutions and possible integration into future electric vehicles. Nevertheless, these new devices are poised to find use in various portable and low-power applications, especially when opportunities to recharge are scarce.

The US government aims to push microelectronics research forward. But maintaining competitiveness in the long term will require embracing uncertainty.

Facing a power wall and the limit of physics, chip makers are in a constant battle to reengineer and re-evaluate ways to build a better CPU.

Physicist Federico Faggin is none other than the inventor of both the microprocessor and silicon gate technology, which spawned the explosive progress in computer technology we have witnessed over the past five decades. He is also probably the world’s most well rounded idealist alive. Mr. Faggin approaches idealism from both a deeply technical and a deeply personal, experiential perspective. In this interview, Essentia Foundation’s Natalia Vorontsova engages in an open, free-ranging but very accessible conversation with Mr. Faggin.

TSMC mulls A14, A10 process technologies in the next few years.

A research group from Tohoku University and RIKEN has developed a high-speed, high-sensitivity terahertz-wave detector operating at room temperature, paving the way for advancements in the development of next generation 6G/7G technology.

Details of their breakthrough were published in the journal Nanophotonics on November 9, 2023.

The enhancement of current communications speeds will rely on terahertz (THz) waves. THz waves are electromagnetic waves within the THz range, which falls between the microwave and infrared portions of the electromagnetic spectrum, typically spanning frequencies from 300 gigahertz to 3 THz.

Quantum computers have the potential to outperform conventional computers on some tasks, including complex optimization problems. However, quantum computers are also vulnerable to noise, which can lead to computational errors.

Engineers have been trying to devise fault-tolerant quantum computing approaches that could be more resistant to noise and could thus be scaled up more robustly. One common approach to attain fault-tolerance is the preparation of magic states, which introduce so-called non-Clifford gates.

Researchers at University of Science and Technology of China, the Henan Key Laboratory of Quantum Information and Cryptography and the Hefei National Laboratory recently demonstrated the preparation of a logical magic state with fidelity beyond the distillation threshold on a superconducting quantum processor. Their paper, published in Physical Review Letters, outlines a viable and effective strategy to generate high-fidelity logical magic states, an approach to realize fault-tolerant quantum computing.

The World Wide Web was first tested on Christmas Day in 1990. Tim Berners-Lee and Robert Cailliau set up successful communication between a web browser & server via the Internet.

Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.

CERN is not an isolated laboratory, but rather the focal point for an extensive community that includes more than 17 000 scientists from over 100 countries. Although they typically spend some time on the CERN site, the scientists usually work at universities and national laboratories in their home countries. Reliable communication tools are therefore essential.
