(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

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 ...

Computers that use light rather than electricity to represent and manipulate data could slash the power demands of data centres and simultaneously speed up calculations. Two studies published today ...

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.
