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…
Quantum Back Action Evasion with Reservoir Engineering
Yohei Nishino, James W. Gardner, Yanbei Chen +1
We propose a back-action evading scheme for a free mass that combines reservoir engineering with velocity measurement. The underlying principle follows the double-pass-type speed m…
Teleportation-based Speed Meter for Precision Measurement
Yohei Nishino, James W. Gardner, Yanbei Chen +1
We propose a quantum teleportation-based speed meter for interferometric displacement sensing. Two equivalent implementations are presented: an online approach that uses real-time…
Lindblad estimation with fast and precise quantum control
James W. Gardner, Simon A. Haine, Joseph J. Hope +2
Enhancing precision sensors for stochastic signals using quantum techniques is a promising emerging field of physics. Estimating a weak stochastic waveform is the core task of many…
