Exploring the Robustness of stabilizing controls for stochastic quantum evolutions
Weichao Liang, Kentaro Ohki, Francesco Ticozzi
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 fo…
Optimizing Measurements Sequences for Quantum State Verification
Weichao Liang, Francesco Ticozzi, Giuseppe Vallone
We consider the problem of deciding whether a given state preparation, i.e., a source of quantum states, is accurate, namely produces states close to a target one within a prescrib…
Dissipative Feedback Switching for Quantum Stabilization
Weichao Liang, Tommaso Grigoletto, Francesco Ticozzi
Switching controlled dynamics allows for fast, flexible control design methods for quantum stabilization of pure states and subspaces, which naturally include both Hamiltonian and…
