Performance of multiple filter-cavity schemes for frequency-dependent squeezing in gravitational-wave detectors
Jacques Ding, Eleonora Capocasa, Isander Ahrend +3
Gravitational-wave detectors use state-of-the-art quantum technologies to reduce the noise induced by vacuum fluctuations, via injection of squeezed states of light. Future detecto…

Quantum Linear Time-Translation-Invariant Systems: Conjugate Symplectic Structure, Uncertainty Bounds, and Tomography
Jacques Ding, Hudson A. Loughlin, Vivishek Sudhir
Linear time-translation-invariant (LTI) models offer simple, yet powerful, abstractions of complex classical dynamical systems. Quantum versions of such models have so far relied o…
