Computers that use photons rather than electrons to manipulate data promise greater speed and energy efficiency, and the ...

Two companies have announced photonic devices that could solve specific real-world problems faster and with less energy than conventional computers.

A tech firm has just demonstrated that a computer chip using light and the speed at which it moves for processing handles ...

So little is known about the field that there is no way—at least, not yet—to predict what a truly “useful” quantum computer would look like, how it would perform, what materials or power it would need ...

Scientists have taken a big step toward making faster and more energy-efficient computers by combining light and electricity ...
