Paderborn scientists publish results in scientific journal
With the development of quantum computers, classical cryptography for secure communication threatens to become obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to provide unrestricted security. One example is quantum key distribution, which allows two parties to secure a message using a random secret key. This is generated using quantum particles, usually photons. For this purpose, scientists are increasingly making use of an alphabet based on special properties of light particles, i.e. photons, namely their color composition. Until now, however, there has been no special device to decode the information. ...
