摘要：
We investigate the quantum features, entanglement and resilience to losses, of multiphoton fields generated by optical amplification of photon entangled states. We first report the realization of a class of Microscopic-Macroscopic entangled states of more than 5 x 10(4) photons, based on parametric amplification of single-photon and two-photons states. A non-locality CHSH-type test has been performed on this system. Then, we apply a decoherence model to this Micro-Macroscopic entangled state, showing their high resilience to photon-loss. The theoretical results are in full agreement with many experimental observations.
