The idea to perform data processing with light, without relying on any electronic components, has been around for quite some time. In fact, necessary components such as optical transistors are available. However, up to now they have not gained a lot of attention from computer companies. Continue reading “Switching with single photons: this is a step towards the quantum computer” »
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. An optical switch that can be turned on by a single photon could point toward new designs for both classical and quantum computers.
