(Nanowerk News) By studying the theoretical limits of how light can be used to perform computation, Cornell researchers have uncovered new insights and strategies for designing energy-efficient ...

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 ...

Ternary optical computing systems represent an innovative leap beyond traditional binary computation by utilising three discrete logic states. This approach leverages the intrinsic advantages of ...

TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT, President & CEO: Jun Sawada, Chiyoda-ku, Tokyo)(TOKYO:9432) in cooperation with the University of Tokyo (President: Teruo Fujii, Bunkyo-ku, Tokyo) and ...

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 ...

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.

NTT and OptQC aim to build a 1-million qubit quantum computer based on light, rather than electricity, to enhance reliability, scalability and practicality. Use cases for a practical optical quantum ...

WASHINGTON, Dec. 14—Optics and photonics may one day revolutionize computer technology with the promise of light-speed calculations. Storing light as memory, however, requires devices known as ...

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, ...

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 ...
