Gauss filtered back projection for the reconstruction of the wigner function

Research output: Contribution to journalArticle

Abstract

Optical homodyne tomography is a quantum state determination process, where measured quadrature distributions are averaged with appropriate sampling functions. We propose Gauss filtered back projection when numerically reconstructing the Wigner function. In this way the result is an s-parametrized quasi-probability distribution where the parameter is determined by the filter.
