Relaxation Control of Open Quantum Systems
Nicolò Beato, Gianluca Teza
A fundamental problem in experiments with open quantum systems is to ensure steady-state convergence within a given operational time window. Here, we devise a general state prepara…

Topological Phase Transitions in a Constrained Two-Qubit Quantum Control Landscape
Nicolò Beato, Pranay Patil, Marin Bukov
In optimal quantum control, control landscape phase transitions (CLPTs) indicate sharp changes occurring in the set of optimal protocols, as a physical model parameter is varied. H…

Toward a Theory of Phase Transitions in Quantum Control Landscapes
Nicolò Beato, Pranay Patil, Marin Bukov
Control landscape phase transitions (CLPTs) occur as abrupt changes in the cost function landscape upon varying a control parameter, and can be revealed by non-analytic points in s…
