Query: Quantum information aspects of approximate position measurement   We perform a quantum information analysis for multi-mode Gaussian approximate
position measurements, underlying noisy homodyning in quantum optics. The
"Gaussian maximizer" property is established for the entropy reduction of these
measurements which provides explicit formulas for computations including their
entanglement-assisted capacity. The case of one mode is discussed in detail.
