摘要：

The new process of quantum injection into a parametric amplifier amplifies into a large dimensionality spin-1/2 Hilbert space the quantum superposition properties of the photon couples generated by parametric down conversion. The Wigner function and the field's correlation functions show a decoherence-free, multi-photon Schrodinger-cat behaviour of the emitted field. (C) 1998 Published by Elsevier Science B.V.
