Nonclassical character of statistical mixtures of the single-photon and vacuum optical states
Physical Review A - Atomic, Molecular, and Optical Physics 65:3 (2002) 1-6
Abstract:
The electric-field-quadrature statistics of the ensembles of the vacuum state 0> are nonclassical according to the Vogel criterion. These states were synthesized and measured with an improved pair-production rate achieved by the pulse picking method. The Vogel criterion is generalized to apply to quadrature distributions obtained in interferometrically unstable settings. In addition, a quantitative analysis of statistical errors is given.Quantum-optical catalysis by means of a single photon

Abstract:
We convert coherent states of light into nonclassical coherent superpositions of the vacuum and the single-photon states via conditional measurements on a beamsplitter, employing single photons as "catalysts": they facilitate the conversion without being consumed.Quantum-optical catalysis by means of a single photon
