The computing world is on the cusp of a transformative leap forward, as researchers at the California Institute of Technology (Caltech) have unveiled an all-optical computer capable of achieving clock ...

Subscribe to our newsletter for the latest sci-tech news updates. The research, published in Nature Communications, addresses one of the key challenges to engineering computers that run on light ...

Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.

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 idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the potential for ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

Optical multiplication: a new technique for combining light signals could give optical computers a boost. (Courtesy: iStock/7io) Researchers in Russia and the UK have proposed a new and simple way to ...

Engineers at MIT have developed a modular computer chip with components that can communicate using flashes of light. This could allow for electronics that can easily be upgraded with new sensors or ...

A research team has developed an optical computing system for AI and machine learning that not only mitigates the noise inherent to optical computing but actually uses some of it as input to help ...
