Multi-level Random-Telegraph Noise Mitigation using a Single Spectator Qubit

Yanan Liu, Hongting Song, Areeya Chantasri +1

Preserving quantum coherence in the presence of environmental noise is one of the principal challenges for quantum technologies. Noise mitigation using spectator qubits (SQs) has r…

Time-dependent multiparameter estimation for quantum experiments via online-offline sequential Monte-Carlo method

Chattamas Manoworakul, Jason F. Ralph, Nattaphong Wonglakhon +1

While typical online estimation methods can estimate the multiparameter dynamics of many systems, they may not be sufficient for a system with highly noisy measurement and rapid de…

Quantum trajectories for time-binned data and their closeness to fully conditioned quantum trajectories

Nattaphong Wonglakhon, Areeya Chantasri, Howard M. Wiseman

Quantum trajectories are dynamical equations for quantum states conditioned on the results of a time-continuous measurement, such as a continuous-in-time current . Recent…

Quantum state-preparation control in noisy environment via most-likely paths

Wirawat Kokaew, Thiparat Chotibut, Areeya Chantasri

Finding controls for open quantum systems needs to take into account effects from unwanted environmental noise. Since actual realizations or states of the noise are typically unkno…

Quantum State Smoothing for Linear Gaussian Systems

Kiarn T. Laverick, Areeya Chantasri, Howard M. Wiseman

Quantum state smoothing is a technique for assigning a valid quantum state to a partially observed dynamical system, using measurement records both prior and posterior to an estima…

Tracking Quantum Dynamics in an Optical Cavity for Recovering Purity and Squeezing via Quantum State Smoothing

Shota Yokoyama, Kiarn T. Laverick, David McManus +6

Tracking the dynamics of a quantum system is conventionally achieved by monitoring the system continuously in time and filtering the information contained in measurement records vi…
