British boffins have made a breakthrough in quantum cryptography, an advanced code-making technology which is theoretically uncrackable, by developing a single photon-emitting diode. The researchers from the University of Cambridge and Toshiba have discovered a way of incorporating semiconductor nano-technology into an LED so they can trigger the emission of single photons at regulated times.

This is important because the security of optical quantum cryptography relies on sending a single photon carrying digital information between two parties exchanging encoded information.
