This research proposes leveraging anti-squeezed Schrödinger cat states in optical interferometers to enhance detection sensitivity and robustness against losses compared to standard Gaussian squeezed states. By optimizing antisqueezing parameters for realistic experimental constraints, the study addresses critical noise reduction challenges essential for advancing precision quantum metrology.
Using anti-squeezed Schr\"odinger cat states for detection of a given phase shift
arXiv:2603.02038v2 Announce Type: replace Abstract: We propose to use the antisqueezing-enhanced non-Gaussian Schr\"odinger cat quantum states of the probing light for the task of detection of a given phase shift in optical interferometers. We show that the antisqueezing allows to increase the robustness of the setup to optical losses. We find the optimal degrees of the antisqueezing for experimentally achievable values of the Schr\"odinger cat amplitude and the optical losses and compare the resulting sensitivity with the one provided by the Gaussian squeezed states.
