Abstract
Squeezed-states of the radiation field can be generated by degenerate parametric amplification. In this paper, an analysis of a DC pumped degenerate Josephson parametric amplifier is presented. The quantum Langevin equations for the fully quantized system are derived. The degree of squeezing that could be obtained below the threshold for parametric oscillations is calculated by linearizing the corresponding quantum Langevin equations.
