Abstract

By using hybrid photodetectors we exploited the photon-number correlations existing in bipartite optical states to demonstrate the effect of multiple-photon subtraction on the generation of conditional states in the pulsed regime. We operated on both classical and quantum Gaussian bipartite states in the mesoscopic regime without background subtraction and corrections. The obtained conditional states are non-Gaussian in nature, thus particularly useful for applications to Quantum Information. All the experimental results are in excellent agreement with theoretical models.
