Radiative and non-radiative photokinetics alteration inside a single metallic nanometric aperture
Jerome Wenger, Benoit Cluzel, Jose Dintinger +6
We resolve the photokinetic rates enhancement of Rhodamine 6G molecules diffusing in a water-glycerol mixture within a single nanometric aperture milled in an opaque aluminium film…
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…
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…
Pulsed homodyne measurements of femtosecond squeezed pulses generated by single-pass parametric deamplification
J. Wenger, R. Tualle-Brouri, P. Grangier
A new scheme is described for pulsed squeezed light generation using femtosecond pulses parametrically deamplified through a single pass in a thin (0.1mm) potassium niobate KNbO3 c…
Non-gaussian statistics from individual pulses of squeezed light
J. Wenger, R. Tualle-Brouri, P. Grangier
We describe the observation of a degaussification protocol that maps individual pulses of squeezed light onto non-Gaussian states. This effect is obtained by sending a small fracti…
