Researchers build an all-optical transistor

An optical switch that can be turned on by a single photon could point toward new designs for both classical and quantum computers.
Optical computing — using light rather than electricity to perform calculations — could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations exponentially faster than classical computers.
