Post-processed estimation of quantum state trajectories
Soroush Khademi, Jesse J. Slim, Kiarn T. Laverick +5
Weak quantum measurements enable real-time tracking and control of dynamical quantum systems, producing quantum trajectories -- evolutions of the quantum state of the system condit…
Counterfactual quantum measurements
Ingita Banerjee, Kiarn T. Laverick, Howard M. Wiseman
Counterfactual reasoning plays a crucial role in exploring hypothetical scenarios, by comparing some consequent under conditions identical except as results from a differing antece…
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…
Quantum state smoothing when Alice assumes the wrong type of monitoring by Bob
Areeya Chantasri, Kiarn T. Laverick, Howard M. Wiseman
An open quantum system leaks information into its environment. In some circumstances it is possible for an observer, say Alice, to recover that information, as a classical measurem…
Inequivalent ways to apply semi-classical smoothing to a quantum system
Kiarn T. Laverick, Areeya Chantasri, Howard M. Wiseman
In this paper, we correct a mistake we made in [Phys. Rev. Lett. , 190402 (2019)] and [Phys. Rev. A , 012213 (2021)] regarding the Wigner function of th…
A Retrodictive Approach to Quantum State Smoothing
Mingxuan Liu, Valerio Scarani, Alexia Auffèves +1
Smoothing is a technique for estimating the state of an imperfectly monitored open system by combining both prior and posterior measurement information. In the quantum regime, curr…
