(Nanowerk News) By studying the theoretical limits of how light can be used to perform computation, Cornell researchers have uncovered new insights and strategies for designing energy-efficient ...

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 ...

(Nanowerk News) Conventional computer processors have pretty much maxed out their “clock speeds” — a measurement of how fast they can toggle on and off — due to limitations of electronic switching.

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 ...

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

“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 ...

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 ...

The constant scaling of AI applications and other digital technologies across industries is beginning to tax the energy grid due to its intensive energy consumption. Digital computing's energy and ...
