This paper investigates waveform estimation (tracking) of the time-varying force in a two-level optomechanical system with backaction noise by Kalman filtering. It is assumed that the backaction and measurement noises are Gaussian and white. By discretizing the continuous-time optomechanical system, the state of the resulting system can be estimated by the unbiased minimum variance Kalman filtering. Then an estimator of the time-varying force is obtained, provided that the external force is…

Optimal State Estimation for Cavity Optomechanical Systems.
Taking into account nontrivial experimental noise sources, such as colored laser noise and spurious mechanical modes, a realistic state-space model is implemented and the conditional system state is obtained, i.e., conditioned on previous measurements, with a minimal least-squares estimation error.
Signal Tracking Beyond the Time Resolution of an Atomic Sensor by Kalman Filtering.
Comparing the accuracy of the atomic statistical model and the reliability of the Kalman filter are confirmed, allowing recovery of waveform details far briefer than the sensor's intrinsic time resolution, and the method evades the trade-off between sensitivity and time resolution in coherent sensing.
Coherent Cancellation of Backaction Noise in optomechanical Force Measurements
Optomechanical detectors have reached the standard quantum limit in position and force sensing where measurement backaction noise starts to be the limiting factor for the sensitivity. A strategy to

Quantum-Enhanced Optical-Phase Tracking
The best precision for optical-phase tracking has until now been limited by the quantum vacuum fluctuations of coherent light, but this work surpasses this coherent-state limit by using a continuous-wave beam in a phase-squeezed quantum state.
