Abstract
Quantum fluctuations of a phase-insensitive amplifier are studied when the quantum fluctuations of the input field are correlated with the amplifier's internal modes. It is found that noise-free quantum amplification can be achieved under certain conditions and only requires finite correlation between the quantum fluctuations of the input field and the amplifier's internal mode. © 1993 The American Physical Society.
