    "abstract": "Two-photon loss mechanisms often accompany a Kerr nonlinearity. The kinetic\ninductance exhibited by superconducting transmission lines provides an example\nof a Kerr-like nonlinearity that is accompanied by a nonlinear resistance of\nthe two-photon absorptive type. Such nonlinear dissipation can degrade the\nperformance of amplifiers and mixers employing a Kerr-like nonlinearity as the\ngain or mixing medium. As an aid for parametric amplifier design, we provide a\nquantum analysis of a cavity parametric amplifier employing a Kerr nonlinearity\nthat is accompanied by a two-photon absorptive loss. Because of their\nusefulness in diagnostics, we obtain expressions for the pump amplitude within\nthe cavity, the reflection coefficient for the pump amplitude reflected off of\nthe cavity, the parametric gain, and the intermodulation gain. Expressions by\nwhich of the degree of squeezing can be computed are also presented.",
