Detection methods for optimal target reflectivity estimation with two-mode squeezed vacuum probes
Harel Radia, Tuvia Gefen, Nadav Katz
Target reflectivity estimation using a two-mode squeezed vacuum (TMSV) probe offers a theoretical advantage over classical schemes, but realizing this potential under the measureme…
Gaussian Quantum Metrology with Realistic Linear Sensors
Jacques Ding, James W. Gardner, Tuvia Gefen +1
Quantum sensing promises enhanced precision, but the usual quantum Cramer Rao bound can be too optimistic for realistic linear sensors, where squeezing, filtering, and loss reshape…
Stochastic signal sensing with finite energy and dead time at the fundamental quantum limit
James W. Gardner, Tuvia Gefen, Matteo Fadel
State preparation, measurement, and reset operations take finite time and use finite energy in realistic experiments, yet the impact of this on optimal quantum metrological protoco…
Optimal quantum metrology protocols with erasure qubits
Michal Arieli, Alex Retzker, Tuvia Gefen
We investigate the precision limits and optimal protocols for sensing single qubit signals in the presence of erasure noise. We study a hierarchy of precision limits achievable wit…
Quantum superresolution and noise spectroscopy with quantum computing
James W. Gardner, Federico Belliardo, Gideon Lee +2
Quantum metrology of an incoherent signal is a canonical sensing problem related to superresolution and noise spectroscopy. We show that quantum computing can accelerate searches f…
Extending the dynamic range in quantum frequency estimation with sequential weak measurements
Su Direkci, Manuel Endres, Tuvia Gefen
Quantum metrology explores optimal quantum protocols for parameter estimation. In the context of optical atomic clocks, conventional protocols focus on optimal input states and mea…
