GHz QKD at telecom wavelengths using up-conversion detectors
R. T. Thew, S. Tanzilli, L. Krainer +6
We have developed a hybrid single photon detection scheme for telecom wavelengths based on nonlinear sum-frequency generation and silicon single-photon avalanche diodes (SPADs). Th…
Quantum superposition and entanglement of mesoscopic plasmons
Sylvain Fasel, Matthaeus Halder, Nicolas Gisin +1
Quantum superpositions and entanglement are at the heart of the quantum information science. There have been only a few investigations of these phenomena at the mesoscopic level, d…
Mid-Infrared Single Photon Counting
Guilherme Temporao, Sebastien Tanzilli, Hugo Zbinden +4
We report a procedure to detect mid-infrared single photons at 4.65 um via a two-stage scheme based on Sum Frequency Generation, using a Periodically Poled Lithium Niobate (PPLN) n…
Implementation of continuous variable quantum cryptography in optical fibres using a go-&-return configuration
Matthieu Legre, Hugo Zbinden, Nicolas Gisin
We demonstrate an implementation of quantum key distribution with continuous variables based on a go-&-return configuration over distances up to 14km. This configuration leads to s…
Quantum cloning
Valerio Scarani, Sofyan Iblisdir, Nicolas Gisin +1
The impossibility of perfectly copying (or cloning) an arbitrary quantum state is one of the basic rules governing the physics of quantum systems. The processes that perform the op…
From Bell's Theorem to Secure Quantum Key Distribution
Antonio Acin, Nicolas Gisin, Lluis Masanes
Any Quantum Key Distribution (QKD) protocol consists first of sequences of measurements that produce some correlation between classical data. We show that these correlation data mu…
