Quantum noise limited interferometric measurement of atomic noise: towards spin squeezing on the Cs clock transition
Daniel Oblak, Jens K. Mikkelsen, Wolfgang Tittel +5
We investigate theoretically and experimentally a nondestructive interferometric measurement of the state population of an ensemble of laser cooled and trapped atoms. This study is…
Quantum communications with time-bin entangled photons: long distance quantum teleportation and quantum repeaters
N. Gisin, I. Marcikic, H. de Riedmatten +2
Using 2 km of standard telecom optical fibres, we teleport qubits carried by photons of 1310 nm wavelength to qubits in another lab carried by a photons of 1550 nm wavelength. The…
Photonic Entanglement for Fundamental Tests and Quantum Communication
Wolfgang Tittel, Gregor Weihs
Entanglement is at the heart of fundamental tests of quantum mechanics like tests of Bell-inequalities and, as discovered lately, of quantum computation and communication. Their te…
Highly efficient photon-pair source using a Periodically Poled Lithium Niobate Waveguide
S. Tanzilli, H. de Riedmatten, W. Tittel +5
We report on a new kind of correlated photon-pair source based on a waveguide integrated on a Periodically Poled Lithium Niobate substrate. Using a pump laser of a few micro-Watts…
Quantum secret sharing using pseudo-GHZ states
W. Tittel, H. Zbinden, N. Gisin
We present a setup for quantum secret sharing using pseudo-GHZ states based on energy-time entanglement. In opposition to true GHZ states, our states do not enable GHZ-type tests o…
Quantum cryptography and long distance Bell experiments: How to control decoherence
N. Gisin, J. Brendel, J-D. Gautier +5
Several mechanisms that affect one and two photon coherence in optical fibers and their remedies are discussed. The results are illustrated on quantum cryptography experiments and…
