Loss-tolerant detection of squeezed states in the 2 um region
K. M. Kwan, T. G. McRae, J. Qin +9
Squeezed states of light enable quantum-enhanced measurements but are limited by optical loss, particularly at 2 um where photodiode efficiency is low. We report the first loss-tol…

Squeezing at the normal-mode splitting frequency of a nonlinear coupled cavity
Jonas Junker, Jiayi Qin, Vaishali B. Adya +5
Coupled optical cavities, which support normal modes, play a critical role in optical filtering, sensing, slow-light generation, and quantum state manipulation. Recent theoretical…

Quantum enhanced balanced heterodyne readout for differential interferometry
Daniel W. Gould, Vaishali B. Adya, Sheon S. Y. Chua +8
Conventional heterodyne readout schemes are now under reconsideration due to the realization of techniques to evade its inherent 3 dB signal-to-noise penalty. The application of hi…
