A new and much faster quantum cryptography protocol has been developed: Usually, quantum cryptography is done with photons that can be in two different states. Using eight different states, cryptographic keys can be generated much faster and with much more robustness against interference.

Quantum cryptography is one of the most promising quantum technologies of our time: Exactly the same information is generated at two different locations, and the laws of quantum physics guarantee that no third party can intercept this information. This creates a code with which information can be perfectly encrypted.
