Tomographic recovering of radiation state's Wigner distribution: a novel tool for characterizing optical devices

摘要

Quantum homodyne tomography (QHT) is the most successful technique for measuring the quantum state of light. It is based on numerical manipulation of balanced homodyne data. So far QHT is the only method successfully employed in a number of experiments to reconstruct the quantum state. We report QHT as a tool for the quantum characterization of optical devices. The goal is to link the estimation of relevant parameters with the results of homodyne detection.
