We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although the ...

“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 ...

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 ...

(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 ...

Intel says its work on switching from copper I/O to optical fiber has taken a big step forward in high-speed data transmission. At this year's Optical Fiber Communication Conference in San Francisco, ...

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 ...
