Quantum Cryptography
with Entangled Photons

We aim at the development of a plug&play-system for absolute secure communication and its necessary enviroment (e.g. network structures, hard- and soft ware,...) using the highly fascinating properties of quantum physics.

Quantum cryptography is a superior technology which overcomes limitations and drawbacks of classical cryptographic schemes by utilizing quantum physical effects.
The appeal of quantum cryptography is that its security is based on the laws of nature. In contrast to existing classical schemes of Key Distribution, Quantum Key Distribution does not invoke the transport of the key, since it is created at the sender and receiver site immediately. Furthermore, the key is created from a completely random sequence, which is in general an extremely diffcult task in classical schemes. Finally, eavesdropping is easily detected due to the fragile nature of the qubits invoked for the quantum key distribution.
