Bayesian frequency estimation at the fundamental quantum limit
James W. Gardner, Tuvia Gefen, Ethan Payne +6
Searching for a weak signal at an unknown frequency is a canonical task in experiments probing fundamental physics such as gravitational-wave observatories and ultra-light dark mat…

Stochastic waveform estimation at the fundamental quantum limit
James W. Gardner, Tuvia Gefen, Simon A. Haine +4
Although measuring the deterministic waveform of a weak classical force is a well-studied problem, estimating a random waveform, such as the spectral density of a stochastic signal…
