- Abstract: The protocol of quantum reading refers to the quantum enhanced retrieval of
information from an optical memory, whose generic cell stores a bit of
information in two possible lossy channels. In the following we analyze the
case of a particular class of optical receiver, based on photon counting
measurement, since they can be particularly simple in view of real
applications. We show that a quantum advantage is achievable when a transmitter
based on two-mode squeezed vacuum (TMSV) states is combined with a photon
counting receiver, and we experimentally confirm it. In this paper, after
introducing some theoretical background, we focus on the experimental
realisation, describing the data collection and the data analysis in detail.
