Time-resolved homodyne characterization of individual quadrature-entangled pulses
Jerome Wenger, Alexei Ourjoumtsev, Rosa Tualle-Brouri +1
We describe a simple and efficient setup to generate and characterize femtosecond quadrature-entangled pulses. Quantum correlations equivalent to about 2.5 dB squeezing are efficie…
An atom interferometer for measuring loss of coherence from an atom mirror
Jerome Esteve, David Stevens, Christine Aussibal +3
We describe an atom interferometer to study the coherence of atoms reflected from an evanescent wave mirror. The interferometer is sensitive to the loss of phase coherence induced…
Contextual objectivity and the quantum formalism
Philippe Grangier
The new orthodoxy of quantum mechanics (QM) based on the decoherence approach requires many-worlds as an essential ingredient for logical consistency, and one may wonder what statu…
Atom chips in the real world: the effects of wire corrugation
Thorsten Schumm, Jèrôme Estève, Christine Aussibal +7
We present a detailed model describing the effects of wire corrugation on the trapping potential experienced by a cloud of atoms above a current carrying micro wire. We calculate t…
Pulsed squeezed vacuum characterization without homodyning
J. Wenger, J. Fiurasek, R. Tualle-Brouri +2
Direct photon detection is experimentally implemented to measure the squeezing and purity of a single-mode squeezed vacuum state without an interferometric homodyne detection. Foll…
Proposal for a loophole-free Bell test using homodyne detection
R. Garcia-Patron Sanchez, J. Fiurasek, N. J. Cerf +3
We propose a feasible optical setup allowing for a loophole-free Bell test with efficient homodyne detection. A non-gaussian entangled state is generated from a two-mode squeezed v…
