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.

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.
JERUSALEM, Dec 26 (Reuters) — Israel’s government agreed to give Intel (INTC.O) a $3.2 billion grant for a new $25 billion chip plant it plans to build in southern Israel, both sides said on Tuesday, in what is the largest investment ever by a company in Israel.
The news comes as Israel remains locked in a war with Palestinian militant group Hamas in the wake of the Oct. 7 Hamas attack on Israel. It also is a big show of support by a major U.S. company and a generous offer by Israel’s government at a time when Washington has increased pressure on Israel to take further steps to minimise civilian harm in Gaza.
Shares of Intel, which has a bit less than 10% of its global workforce in Israel, opened up 2.73% at $49.28 on Nasdaq.
The processors of most computers work in series, performing one instruction at a time. This limits their ability to perform certain types of tasks in a reasonable period. An approach based on arrays of simultaneously interacting molecular switches could enable previously intractable computational problems to be solved.
