12 Hilbert space the quantum entanglement and superposition properties of the photon couples generated by parametric downconversion. The structure of the Wigner function and of the field’s correlation functions shows a decoherence-free multiphoton Schroedinger-cat behavior of the emitted field which is largely detectable against the squeezed-vacuum noise.
