Abstract

A general model for nonlinear amplification of a Single field mode involves the bosonic degree of freedom of the field mode. plus other degrees of freedom describing the amplifier. The state in which the amplifier is prepared. and the initial state of the field. are uncorrelated. (The amplifier cannot anticipate the field state.) During amplification, the field and amplifier evolve according to a unitary transformation. and in the transformed state the field and amplifier are correlated. Correlations increase die noise in the amplified field. but without thew there could be no amplification at all.
