Computing lighting that looks real remains complex and inefficient, as the necessary consideration of all possible paths light can take remains too costly to be performed for every pixel in real-time.

Computers created within the next two decades could revolve around a technology in which laser beams converge inside crystals the size of sugar cubes, forming holographic images for processing huge ...

A simple computer that marries the mind-boggling computing power of quantum mechanics with the ease of manipulating light has been built by researchers at the University of Rochester. The device ...

Light-based computers are expected to come around in ten years, but the technical challenges and engineering problems that they pose will have to be solved before it becomes a reality. However, it ...
