Optimal zeno dragging for quantum control: a shortcut to zeno with action-based scheduling optimization

P Lewalle, Y Zhang, KB Whaley - PRX Quantum, 2024 - APS
The quantum Zeno effect asserts that quantum measurements inhibit simultaneous unitary
dynamics when the “collapse” events are sufficiently strong and frequent. This applies in the …

Unraveling metastable Markovian open quantum systems

CA Brown, K Macieszczak, RL Jack - Physical Review A, 2024 - APS
We analyze the dynamics of metastable Markovian open quantum systems by unraveling
their average dynamics into stochastic trajectories. We use quantum reset processes as …

[HTML][HTML] Stochastic entropy production associated with quantum measurement in a framework of Markovian quantum state diffusion

CL Clarke, IJ Ford - Entropy, 2024 - pmc.ncbi.nlm.nih.gov
The reduced density matrix that characterises the state of an open quantum system is a
projection from the full density matrix of the quantum system and its environment, and there …

Stochastic entropy production for dynamical systems with restricted diffusion

J Dexter, IJ Ford - arXiv preprint arXiv:2302.01882, 2023 - arxiv.org
Modelling the evolution of a system using stochastic dynamics typically implies a greater
subjective uncertainty in the adopted system coordinates as time progresses, and stochastic …

Memory in a sequence of weak and short duration measurements of non-commuting observables

SM Walls, IJ Ford - arXiv preprint arXiv:2402.08737, 2024 - arxiv.org
Sequential projective measurements of non-commuting observables destroy information
about previous measurement outcomes, but weak measurements conducted over short …

Three components of stochastic entropy production associated with the quantum Zeno and anti-Zeno effects

A Kinikar, IJ Ford - arXiv preprint arXiv:2303.10196, 2023 - arxiv.org
We investigate stochastic entropy production in a two-level quantum system that performs
Rabi oscillations while undergoing quantum measurement brought about by continuous …
