Studying physics can be very useful—even when it comes to machine learning. A digital "super-brain" with built-in knowledge ...

Optical drives let your computer read and interact with discs like CDs, DVDs, and Blu-rays. While nearly every computer had them a few years ago, they're rare to see on new computers now. If you need ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

“Energy efficiency of electronic digital processors is primarily limited by the energy consumption of electronic communication and interconnects. The industry is almost unanimously pushing towards ...

Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing. The system, developed in Cambridge, U.K., is designed to handle optimization tasks ...

This new type of optical memory unit,called a programmable photonic latch, is fast and scalable. It could offer a high-speed silicon photonics solution for volatile memory. WASHINGTON — Researchers ...

Designing materials that steer light is a slow kind of trial and error. Each candidate structure must be tested in computer ...
