PRACTICAL QUANTUM KEY DISTRIBUTION USING POLARIZATION ENTANGLED STATES
Fabio Antonio Bovino, Pietro Varisco, Anna Martinoli +6 more
We present the architecture and recent experimental results for a quantum key distribution system realized at Elsag spa Quantum Optics Laboratory with a key distribution rate suitable for practical industrial applications. The current system can reliably distribute secure cryptographic keys at a rate of 1,500 bit per second and higher at a few hundred meters, with a quantum bit error rate lower than 1%.
