- Abstract: Quantum properties of light, which are crucial resources for Quantum
Technologies, are quite fragile in nature and can be degraded and even
concealed by the environment. We show, both theoretically and experimentally,
that mesoscopic twin-beam states of light can preserve their nonclassicality
even in the presence of major losses and different types of noise, thus
suggesting their potential usefulness to encode information in Quantum
Communication protocols. We develop a comprehensive general analytical model
for a measurable nonclassicality criterion and find thresholds on noise and
losses for the survival of entanglement in the twin beam.
