A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.

Lumai has unveiled what it describes as the world’s first optical computing system capable of running a billion parameter ...

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.

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 ...

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 ...

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 ...

Xanadu Quantum Technologies is a Canadian quantum computing hardware and software with US$145 million of funding. In May, 2021, they raised US$100M in Series B financing. Bessemer Venture Partners led ...

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 ...

Modular optical computer chip allows stackable swappable functions By Michael Irving June 20, 2022 MIT engineers have developed a new modular computer chip that uses flashes of light to communicate ...
