Brain-bending crypto
Current systems of quantum cryptography are not fail-safe because they emit more than one photon (particles of light) at a time, essentially allowing a hacker to break certain parts of a code without being detected.
"Single photons are rather like magic bullets of molecular biology, in that the laws of quantum mechanics result in the certain failure of any attempt to intercept the information," said Toshiba Research's professor Michael Pepper.
