We report on the application of a fast physical random bit generator based on chaotic semiconductor lasers to generation of random pulse sequences at 1.0 Gpps (giga pulses per second) in a quantum key distribution system. We generate a random binary signal at 1.0 Gbps and use it to modulate the phase of optical pulses transmitted in the differential-phase-shift quantum-key-distribution (DPS-QKD) scheme.
Imperfect practical conditions limit communication speed of quantum cryptography. Here we implement differential phase shift quantum key distribution with up-conversion assisted hybrid photon detector to achieve 1.3 M bits/s secure key rate over a 10-km fiber.
Quantum-key distribution has been studied as an ultimate method for secure communications, and now it is emerging as a technology that can be deployed in real fiber networks. Here, we present our QKD experiments based on the differential- phase-shift QKD protocol. A DPSQKD system has a simple configuration that is easy to implement with conventional optical communication components, and it is suitable...
