A computer chip that processes data as pulses of light rather than electrical signals has, for the first time, run a suite of ...

In 2009, Jeremy O'Brien, a professor at the University of Bristol, published a research paper describing how to repurpose on-chip optical components originally developed by the telecom industry to ...

A computer chip that calculates with light instead of electrical current has passed a milestone that researchers have chased for decades: it can run real neural-network tasks, on a sliver of silicon, ...

AI models are power hogs. As the algorithms grow and become more complex, they’re increasingly taxing current computer chips. Multiple companies have designed chips tailored to AI to reduce power draw ...

While it's no replacement for either computer, the new device is a powerful alternative for addressing some very practical challenges. Reading time 3 minutes In a world of ever-improving computing ...

As artificial intelligence grows more powerful, so does its appetite for speed and energy. The quest for faster, smarter systems has driven researchers to an unlikely ally—light itself. A new study by ...

Physicists present a nanometer-sized light antenna with electrically modulated surface properties -- a breakthrough that could pave the way for faster computer chips. Physicists from Würzburg present ...

A Seattle-area startup called Pattern Computer is developing a rapid COVID-19 test based on patterns in light from spit, one of several projects moving ahead from the 7-year-old company that designed ...
