Phase-Sensitive Crystal-Edge Effects in Linear Optical Parametric Oscillators: Why Nominally Identical Squeezers Behave Differently
Jonas Junker, Donghwa Lee, Reda Louahaj +5
Efficient and reproducible squeezed-light sources are essential for quantum information processing and precision metrology. Compact linear standing-wave optical parametric oscillat…
Realization of an all-optical effective negative-mass oscillator for coherent quantum noise cancellation
Nived Johny, Jonas Junker, Bernd Schulte +3
We report the realization of an all-optical, tabletop effective-negative-mass oscillator (ENMO) scheme capable of canceling quantum noise when cascaded with an opto-mechanical sens…
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…
