Semiconductor lasers, unlike bulky gas lasers and fiber lasers, are tiny, energy efficient, and highly controllable. The one thing they can’t do is deliver their competitor’s steel-slicing brightness.In results reported last week in Nature, a group of researchers at Kyoto University, led by IEEE Fellow Susumu Noda, has taken a…

Bob Kahn on the Birth of “Inter-networking”

IEEE Spectrum recently published a profile of Vint Cerf, who together with Bob Kahn developed what later became known as TCP/IP, the suite of protocols that power the Internet. That article didn’t detail the events leading up to their influential technical collaboration, though. So IEEE Spectrum talked with Kahn to…

The math that explains why a donut is really the same shape as coffee mug but not a waste bin could be the key to making quantum computers practicable. Two teams of researchers have used topology, a centuries-old field of mathematics, and a new kind of “quasi-particle” to come up…

The future of the U.S. cryptocurrency industry hangs in the balance after the Securities and Exchange Commission (SEC) sued cryptocurrency exchanges Binance and Coinbase. The cases hinge on the technology’s ambiguous legal status, but if the SEC wins the outcome may well not be ambiguous at all. Some outcomes could…

Quantum Repeaters for a Global Quantum Internet

The physics that makes quantum computers tick is very sensitive to disturbances. Currently this means that these computers struggle to share their data with each other over long distances in the way that classical computers readily can, where an intermediate calculation might be handed off from one server to another…

The Semiconductor Industry’s Most Important Tool Goes Green

12 Ιουνίου 2023 by paulkokos

In the complex quest to keep increasing the density of transistors, extreme ultraviolet (EUV) lithography is the most critical tool. Costing more than US $100 million, these trailer-size systems bounce near x-ray wavelength light off of a complex cascade of mirrors and onto silicon wafers to create patterns with nanometer-scale…

A Critical Look at AI-Generated Software
