Description
Optical parametric amplifiers/oscillators can produce squeezed light, which has reduced noise in one quadrature at the expense of increased noise in the other and shows promise in optical sensors and many quantum applications. However, highly squeezed light is difficult to measure due to contributions from a plethora of noise sources. In this talk, we quantify fundamental noise limits on squeezing measurements, providing a practical framework for designing and evaluating future integrated squeezed-light systems.
We discuss this noise model in the context of ongoing experimental work on generating and detecting squeezed light on-chip with an SU(1,1) interferometer on the thin-film lithium niobate platform. A second optical parametric amplifier, placed after the initial squeezer, provides a loss-tolerant means of detecting the squeezing.
