Two-photon gateway in one-atom cavity quantum electrodynamics
A. Kubanek, A. Ourjoumtsev, I. Schuster +4
Single atoms absorb and emit light from a resonant laser beam photon by photon. We show that a single atom strongly coupled to an optical cavity can absorb and emit resonant photon…
Increasing entanglement between Gaussian states by coherent photon subtraction
Alexei Ourjoumtsev, Aurelien Dantan, Rosa Tualle-Brouri +1
We experimentally demonstrate that the entanglement between Gaussian entangled states can be increased by non-Gaussian operations. Coherent subtraction of single photons from Gauss…
Quantum homodyne tomography of a two-photon Fock state
Alexei Ourjoumtsev, Rosa Tualle-Brouri, Philippe Grangier
We present a continuous-variable experimental analysis of a two-photon Fock state of free-propagating light. This state is obtained from a pulsed non-degenerate parametric amplifie…
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…
