A Trade-Off Between Path Entanglement and Quantum Sensitivity
Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala
Entanglement often increases quantum measurement schemes' sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, enta…
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…
LIGO Detector Characterization in the first half of the fourth Observing run
S. Soni, B. K. Berger, D. Davis +232
Progress in gravitational-wave astronomy depends upon having sensitive detectors with good data quality. Since the end of the LIGO-Virgo-KAGRA third Observing run in March 2020, de…
Exceptional-point Sensors Offer No Fundamental Signal-to-Noise Ratio Enhancement
Hudson A. Loughlin, Vivishek Sudhir
Exceptional-point (EP) sensors are characterized by a square-root resonant frequency bifurcation in response to an external perturbation. This has lead numerous suggestions for usi…
