Single-Photon LED: Key To Uncrackable Encryption?

Posted by timothy on from the morse-code-writ-small dept.

nut writes: "The BBC are carrying this story of new type of LED so precise that it can emit just one photon of light each time it is switched on. It has been developed by scientists from Toshiba Research Limited and the University of Cambridge. It is described in the journal Science, although I can find no mention of it on their website. One of the applications of this is supposedly uncrackable encryption, due to the law of indeterminacy. This application is described fully in 'The Code Book', by Simon Singh, although the method was only theoretical at the time the book was first published."

    if you want people to think you know what you are talking about, just put ".com" at the end of everything you say.com

    In order to use this tech you will have to create a transistor that can *detect* a single photon.
