OK, the situation isn’t that cut and dried yet, but a recent paper has described a fully programmable, chip-based optical quantum computer. That idea presses all my buttons, and until someone ...

How would the megaFLOPS per watt for an optical computer compare to, say, a modern i7? Report comment. ... If optical devices are 10X as large, the propagation delay will also be 10X. Report comment.

This would enable micron-scale optical devices to be incorporated into future computer chips for high-density communications or into lab-on-a-chip bio-sensing platforms.” ...

In a milestone for scalable quantum technologies, scientists from Boston University, UC Berkeley, and Northwestern University ...

“The all-optical computer realizes linear operations, nonlinear functions, and memory entirely in the optical domain with > 100 GHz clock rates,” they say. Their work paves the way for a new era of ...

For decades, scientists have looked to light as a way to speed up computing. Photonic neural networks—systems that use light ...

To start, they built the first 8-variable optical computer of its kind. The computer uses different intensities of light to compute at the same location where the information is stored. The ...

Researchers at the University of Strathclyde have developed a new method for assembling ultra-small, light-controlling ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers.

A team of researchers from the University of Strathclyde has taken a major step forward in developing next-generation optical ...

Kyushu University researchers have successfully developed an ultra-high-speed optical modulator that can operate at more than 10 times the speed of current devices. This modulator was made thanks ...
