- Abstract: Phase-sensitive amplification of squeezed states is a technique to mitigate
high detection loss, e.g. at 2-micrometre wavelengths. Our analytical model of
amplified squeezed states expands on the effect of phase noise and derives two
practical parameters: the effective measurable squeezing and the effective
detection efficiency. A case study including realistic parameters demonstrates
the benefit of phase-sensitive amplification. We identified the phase noise in
the optical parametric amplifier (OPA) minimally affects the squeezing level,
enabling increased gain of the OPA. This scheme is compatible with proposed
gravitational-wave detectors and consistent with applications in quantum
systems that are degraded by output coupling loss in optical waveguides.
