Experimental study of the spatial distribution of quantum correlations in a confocal Optical Parametric Oscillator
Marcello Martinelli, Nicolas Treps, Sara Ducci +3
We study experimentally the spatial distribution of quantum noise in the twin beams produced by a type II Optical Parametric Oscillator operating in a confocal cavity above thresho…
Stokes operator squeezed continuous variable polarization states
Roman Schnabel, Warwick P. Bowen, Nicolas Treps +3
We investigate quantum correlations in continuous wave polarization squeezed laser light generated from one and two optical parametric amplifiers, respectively. A general expressio…
Experimental investigation of continuous variable quantum teleportation
Warwick P. Bowen, Nicolas Treps, Ben C. Buchler +5
We report the experimental demonstration of quantum teleportation of the quadrature amplitudes of a light field. Our experiment was stably locked for long periods, and was analyzed…
Experimental demonstration of continuous variable polarization entanglement
Warwick P. Bowen, Nicolas Treps, Roman Schnabel +1
We report the experimental transformation of quadrature entanglement between two optical beams into continuous variable polarization entanglement. We extend the inseparability crit…
Recovery of continuous wave squeezing at low frequencies
W. P. Bowen, R. Schnabel, N. Treps +2
We propose and demonstrate a system that produces squeezed vacuum using a pair of optical parametric amplifiers. This scheme allows the production of phase sidebands on the squeeze…
Surpassing the standard quantum limit for optical imaging using non-classical multimode light
N. Treps, U. Andersen, B. Buchler +4
Using continuous wave superposition of spatial modes, we demonstrate experimentally displacement measurement of a light beam below the standard quantum limit. Multimode squeezed li…
