It’s a bright day for computing — literally. Two tech companies have unveiled computer components that use laser light to process information. These futuristic processors could soon solve specific ...

For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers. Physicists led by Chao-Yang Lu and Jian-Wei Pan, both at the ...

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.
