We want faster and faster computers, and light is the fastest thing in the universe. Therefore, light-based computers should ...

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.

Researchers at the University of Pennsylvania have developed a powerful new optical chip that can process almost 2 billion images per second. The device is made up of a neural network that processes ...

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 ...

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 ...

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 ...

Excuse me a moment—I am going to be bombastic, over excited, and possibly annoying. The race is run, and we have a winner in the future of quantum computing. IBM, Google, and everyone else can turn in ...

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 ...
