Phys. Rev. Lett. 92, 153601 (2004) [4 pages]Non-Gaussian Statistics from Individual Pulses of Squeezed LightReceived 20 November 2003; published 13 April 2004 We describe the observation of a “degaussification” protocol that maps individual pulses of squeezed light onto non-Gaussian states. This effect is obtained by sending a small fraction of the squeezed vacuum beam onto an avalanche photodiode, and by conditioning the single-shot homodyne detection of the remaining state upon the photon-counting events. The experimental data provide clear evidence of phase-dependent non-Gaussian statistics. This protocol is closely related to the first step of an entanglement distillation procedure for continuous variables. © 2004 The American Physical Society URL:
