Fast and User-friendly Quantum Key Distribution

چکیده
Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved « plug & play » interferometric system allowing fast key exchange is then introduced. Self-alignment and compensation of birefringence remain. Original electronics implementing the BB84 protocol and allowing user-friendly operation is presented. Key creation with 0.1 photon per pulse at a rate of 486 Hz with a 5.4% QBER – corresponding to a net rate of 210Hz over a 23 Km installed cable was performed.

Towards practical quantum cryptography
Quantum cryptography bases the security of quantum key exchange on the laws of quantum physics and is likely to become the first application employing quantum effects for communication. Here we present performance tests of a new design based on polarization encoding of attenuated, coherent light pulses. Our measurements show that this compact setup can achieve an effective key-bit rate in the k...
متن کاملLimited Resource Semi-Quantum Key Distribution
A semi-quantum key distribution (SQKD) protocol allows a quantum user and a limited “classical” user to establish a shared secret key secure against an allpowerful adversary. In this work, we present a new SQKD protocol where the quantum user is also limited in her measurement capabilities. We describe the protocol, prove its security, and show its noise tolerance is as high as “fully quantum” ...
