Exponential selection and feedback stabilization of invariant subspaces of quantum trajectories

NH Amini, M Bompais, C Pellegrini - SIAM Journal on Control and …, 2024 - SIAM
We show that quantum trajectories become exponentially fast supported by one of their
minimal invariant subspaces. The exponential convergence is established in expectation by …

Exploring the robustness of stabilizing controls for stochastic quantum evolutions

W Liang, K Ohki, F Ticozzi - arXiv preprint arXiv:2311.04428, 2023 - arxiv.org
In this work we analyze and bound the effect of modeling errors on the stabilization of pure
states or subspaces for quantum stochastic evolutions. Different approaches are used for …

On the Robustness of Stability for Quantum Stochastic Systems

W Liang, K Ohki, F Ticozzi - 2023 62nd IEEE Conference on …, 2023 - ieeexplore.ieee.org
We investigate the impact of undesired Markovian couplings to external systems on the
stabilization towards pure states or subspaces of continuously monitored quantum systems …
