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.

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 ...

An optical, in-computer breakthrough being explored by researchers at University of North Carolina at Chapel Hill will let computers run cooler and faster. Light-carrying, miniature wires are ...

A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.
