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…
A photonic quantum information interface
Sebastien Tanzilli, Wolfgang Tittel, Matthaeus Halder +4
Quantum communication is the art of transferring quantum states, or quantum bits of information (qubits), from one place to another. On the fundamental side, this allows one to dis…
Trojan Horse attacks on Quantum Key Distribution systems
N. Gisin, S. Fasel, B. Kraus +2
General Trojan horse attacks on quantum key distribution systems are analyzed. We illustrate the power of such attacks with today's technology and conclude that all system must imp…
Fast and simple one-way Quantum Key Distribution
Damien Stucki, Nicolas Brunner, Nicolas Gisin +2
We present and demonstrate a new protocol for practical quantum cryptography, tailored for an implementation with weak coherent pulses to obtain a high key generation rate. The key…
A Fabry-Perot like two-photon interferometer for high-dimensional time-bin entanglement
Damien Stucki, Hugo Zbinden, Nicolas Gisin
We generate high-dimensional time-bin entanglement using a mode-locked laser and analyze it with a 2-photon Fabry-Perot interferometer. The dimension of the entangled state is limi…
