Quantum jumps in backaction evasion measurements of a light field component

Abstract

Backaction evasion measurements of a quadrature component of the light field vacuum necessarily induce quantum jumps in the photon number. The correlation between measurement results and quantum jump events reveals fundamental nonclassical aspects of quantization.Comment: 3 pages, including 2 figures, contribution for the Technical Digest of the conference on Nonlinear Optics, held August 2000 in Hawai
