Quantum measurements of spatial conjugate variables: Displacement and tilt of a Gaussian beam

Delaubert, Vincent; Treps, Nicolas; Harb, Charles C.; Lam, Ping Koy; Bachor, Hans

Description

We consider the problem of measurement of optical transverse profile parameters and their conjugate variable. Using multi-mode analysis, we introduce the concept of detection noise-modes. For Gaussian beams, displacement and tilt are a pair of transverse profile conjugate variables. We experimentally demonstrate their optimal encoding and detection with a spatial homodyning scheme. Using higher order spatial mode squeezing, we show the sub-shot noise measurements for the displacement and...[Show more]
