Hamiltonians for the photon-number-phase amplifiers
Giacomo Mauro D’Ariano · Physical Review A · 1992
Hamiltonians attaining number-phase amplification are presented. The amplification is driven by a peculiar dependence of the polarization on the phase of the field in a limited frequency range.Received 20 May 1991DOI:https://doi.org/10.1103/PhysRevA.45.3224©1992 American Physical Society
