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 ...

The right lighting can make a world of difference, especially if you spend long hours in front of a computer. But there's more to choosing the best lights for your home office than you might think.
