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…
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…
