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.

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 ...

When it comes to computation, the modern approach seems to involve an enormous bucket of bits, vigorous shaking, and not a lot of explanation of how it all works. If you ever wondered how Excel became ...

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 ...
