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.

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

British researchers have created a new material that could allow for the creation of all-optical computers -- computers that are orders of magnitude faster and power efficient than today's hot, sweaty ...

Fifth-year applied physics Ph.D. candidate Ben Bartlett, postdoctoral scholar Avik Dutt and electrical engineering professor Shanhui Fan proposed a new computer hardware design in November that could, ...

“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 ...

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.

(Phys.org) -- Quantum computers may someday revolutionize the information world. But in order for quantum computers at distant locations to communicate with one another, they have to be linked ...
