چکیده
Quantum cryptography bases the security of key exchange on the laws of quantum physics and will become the first application of quantum information methods. Here we present the design of novel hardware components which enabled the demonstration of secure key exchange over a 23.4 km free-space link.

Practical quantum cryptography for secure free-space communications
Quantum Cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. The security of these transmissions is based on the inviolability of the laws of quantum mechanics and information – theoretically secure postprocessing methods. An adversary can neither successfully tap the ...

متن کاملFree-space quantum network with trusted relay
Nowadays, information security plays an increasingly important role in global communication. Quantum cryptography [1, 2], particularly quantum key distribution (QKD), offers means to expand a secure key between two distant parties, whose security is stemmed from the fundamental laws of quantum mechanics [3–5]. In practice, QKD experiments have been demonstrated over longdistance optical links t...
متن کاملQuantum cryptography and long distance Bell experiments: How to control decoherence
Several mechanisms that affect one and two photon coherence in optical fibers and their remedies are discussed. The results are illustrated on quantum cryptography experiments and on long distance Bell inequality tests.
