10-Mb/s Quantum Key Distribution

10-GHz clock differential phase shift quantum key distribution experiment.

This paper reports the first quantum key distribution experiment implemented with a 10-GHz clock frequency. We used a 10-GHz actively mode-locked fiber laser as a source of short coherent pulses and single photon detectors based on frequency up-conversion in periodically poled lithium niobate waveguides. The use of short pulses and low-jitter upconversion detectors significantly reduced the bit...

High-repetition rate quantum key distribution [6780-10]

The desire for quantum-generated cryptographic key for broadband encryption services has motivated the development of high-transmission-rate single-photon quantum key distribution (QKD) systems. The maximum operational transmission rate of a QKD system is ultimately limited by the timing resolution of the single-photon detectors and recent advances have enabled the demonstration of QKD systems ...

Quantum Authenticated Key Distribution

Quantum key distribution algorithms use a quantum communication channel with quantum information and a classical communication channel for binary information. The classical channel, in all algorithms to date, was required to be authenticated. Moreover, Lomonaco [8] claimed that authentication is not possible using only quantum means. This paper reverses this claim. We design an algorithm for qu...

Quantum Key Distribution - QKD

This paper provides an overview of quantum key distribution targeted towards the computer science community. A brief description of the relevant principles from quantum mechanics is provided before surveying the most prominent quantum key distribution protocols present in the literature. In particular this paper describes the BB84 protocol and its many variants as well as Eckert's approach thro...
