Query: Quantum interferences reconstruction with low homodyne detection
  efficiency   Standard quantum state reconstruction techniques indicate that a detection
efficiency of $0.5$ is an absolute threshold below which quantum interferences
cannot be measured. However, alternative statistical techniques suggest that
this threshold can be overcome at the price of increasing the statistics used
for the reconstruction. In the following we present numerical experiments
proving that quantum interferences can be measured even with a detection
efficiency smaller than $0.5$. At the same time we provide a guideline for
handling the tomographic reconstruction of quantum states based on homodyne
data collected by low efficiency detectors.
