Stabilizing open quantum batteries by sequential measurements

S Gherardini, F Campaioli, F Caruso, FC Binder - Physical Review Research, 2020 - APS
A quantum battery is a work reservoir that stores energy in quantum degrees of freedom.
When immersed in an environment, an open quantum battery needs to be stabilized against …

Experimental noise filtering by quantum control

A Soare, H Ball, D Hayes, J Sastrawan, MC Jarratt… - Nature Physics, 2014 - nature.com
Extrinsic interference is routinely faced in systems engineering, and a common solution is to
rely on a broad class of filtering techniques to afford stability to intrinsically unstable systems …

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 …

Steady-state entanglement by engineered quasi-local Markovian dissipation

F Ticozzi, L Viola - arXiv preprint arXiv:1304.4270, 2013 - arxiv.org
We characterize and construct time-independent Markovian dynamics that drive a finite-
dimensional multipartite quantum system into a target (pure) entangled steady state, subject …

Model robustness for feedback stabilization of open quantum systems

W Liang, NH Amini - Automatica, 2024 - Elsevier
This paper builds upon and expands the findings presented in Liang et al.(2021). Our focus
lies in scenarios where initial states and model parameters remain unknown. In contrast to …

Exploring the robustness of stabilizing controls for stochastic quantum evolutions

W Liang, K Ohki, F Ticozzi - SIAM Journal on Control and Optimization, 2025 - SIAM
In this work we analyze and bound the effect of modeling errors on the stabilization of pure
