Numerical investigation of the quantum fluctuations of optical fields transmitted through an atomic medium

A. Lezama, P. Valente, H. Failache +2

We have numerically solved the Heisenberg-Langevin equations describing the propagation of quantized fields through an optically thick sample of atoms. Two orthogonal polarization…

The quest for three-color entanglement: experimental investigation of new multipartite quantum correlations

K. N. Cassemiro, A. S. Villar, M. Martinelli +1

We experimentally investigate quadrature correlations between pump, signal, and idler fields in an above-threshold optical parametric oscillator. We observe new quantum correlation…

Experimental observation of three-color optical quantum correlations

K. N. Cassemiro, A. S. Villar, P. Valente +2

Quantum correlations between bright pump, signal, and idler beams produced by an optical parametric oscillator, all with different frequencies, are experimentally demonstrated. We…

Direct Production of Tripartite Pump-Signal-Idler Entanglement in the Above-Threshold Optical Parametric Oscillator

A. S. Villar, M. Martinelli, C. Fabre +1

We calculate the quantum correlations existing among the three output fields (pump, signal, and idler) of a triply resonant non-degenerate Optical Parametric Oscillator operating a…

Generation of Bright Two-Color Continuous Variable Entanglement

A. S. Villar, L. S. Cruz, K. N. Cassemiro +2

We present the first measurement of squeezed-state entanglement between the twin beams produced in an Optical Parametric Oscillator (OPO) operating above threshold. Besides the usu…

Noise spectroscopy of non-linear magneto optical resonances in Rb vapor

M. Martinelli, P. Valente, H. Failache +4

Nonlinear magneto-optical (NMO) resonances occurring for near-zero magnetic field are studied in Rb vapor using light-noise spectroscopy. With a balanced detection polarimeter, we…
