摘要：
A novel phase sensitive amplifier/squeezer of entangled two-photon states is adopted to demonstrate the first realization of an all optical multiphoton Schroedinger-Cat state with a large, virtually infinite, signal-to-noise ratio. Because of its intrinsic nonlocal structure the new system is expected to play a relevant role in quantum information and in the basic physics of entanglement.
