Quantum parameter estimation with the Landau-Zener transition
Jing Yang, Shengshi Pang, Andrew N. Jordan
We investigate the fundamental limits in precision allowed by quantum mechanics from Landau-Zener transitions, concerning Hamiltonian parameters. While the Landau-Zener transition…
Prediction and Characterization of Multiple Extremal Paths in Continuously Monitored Qubits
Philippe Lewalle, Areeya Chantasri, Andrew N. Jordan
We examine most-likely paths between initial and final states for diffusive quantum trajectories in continuously monitored pure-state qubits, obtained as extrema of a stochastic pa…
Arrow of Time for Continuous Quantum Measurement
Justin Dressel, Areeya Chantasri, Andrew N. Jordan +1
We investigate the statistical arrow of time for a quantum system being monitored by a sequence of measurements. For a continuous qubit measurement example, we demonstrate that tim…
Rapid estimation of drifting parameters in continuously measured quantum systems
Luis Cortez, Areeya Chantasri, Luis Pedro García-Pintos +2
We investigate the determination of a Hamiltonian parameter in a quantum system undergoing continuous measurement. We demonstrate a computationally rapid yet statistically optimal…
Optimal adaptive control for quantum metrology with time-dependent Hamiltonians
Shengshi Pang, Andrew N. Jordan
Quantum metrology has been studied for a wide range of systems with time-independent Hamiltonians. For systems with time-dependent Hamiltonians, however, due to the complexity of d…
Protecting weak measurements against systematic errors
Shengshi Pang, Jose Raul Gonzalez Alonso, Todd A. Brun +1
In this work, we consider the systematic error of quantum metrology by weak measurements under decoherence. We derive the systematic error of maximum likelihood estimation in gener…
