Quantum-optical catalysis: Generating nonclassical states of light by means of linear optics

Physical Review Letters 88:25 I (2002) 2504011-2504014

Authors:

AI Lvovsky, J Mlynek

Abstract:

The preparation and characterization of a new quantum state of light, a coherent superposition of the single-photon and vaccum states was discussed. This state was generalized by a catalytic process in which the single photon state enabled the interaction without being affected. A transition between a highly classical and a highly nonclassical state of light occurred by changing the amplitude of the target coherent state.

Cabello's nonlocality and linear optics

Physical Review Letters 88:9 (2002) 989011

Abstract:

A study on the quantum nonlocality without inequalities and without probabilities for two observers was performed. Cabello's proposal for nonlocality was challenged and it was shown that nonlinear optics was required for a loophole-free demonstration of Cabello's nonlocality. Cabello had proposed a way of testing the inequality by means of linear optics and used the product of two observable quantities as a single quantum measurement.
