Quantum-optical catalysis: Generating nonclassical states of light by means of linear optics
Physical Review Letters 88:25 I (2002) 2504011-2504014
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.CONTINUOUS-WAVE OPTICAL PARAMETRIC OSCILLATORS AS NEW TOOLS FOR HIGH RESOLUTION SPECTROSCOPY

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.Cabello’s Nonlocality and Linear Optics
