Quantum state measurement by realistic heterodyne detection
arXiv:quant-ph/9511017 · doi:10.1103/PhysRevA.53.2658
Abstract
The determination of the quantum properties of a single mode radiation field by heterodyne or double homodyne detection is studied. The realistic case of not fully efficient photodetectors is considered. It is shown that a large amount of quite {\em precise} information is avalaible whereas the completeness of such information is also discussed. Some examples are given and the special case of states expressed as a finite superposition of number states is considered in some detail.
