On the convergence of the variational quantum eigensolver and quantum optimal control
Marco Wiedmann, Daniel Burgarth, Gunther Dirr +3
When do variational quantum algorithms converge to a globally optimal solution? Despite extensive work, this question remains largely open. We develop a convergence theory for the…
Reachability, Coolability, and Stabilizability of Open Markovian Quantum Systems with Fast Unitary Control
Emanuel Malvetti, Frederik vom Ende, Gunther Dirr +1
Open Markovian quantum systems with fast and full Hamiltonian control can be reduced to an equivalent control system on the standard simplex modelling the dynamics of the eigenvalu…
Exploring the Limits of Controlled Markovian Quantum Dynamics with Thermal Resources
Frederik vom Ende, Emanuel Malvetti, Gunther Dirr +1
Our aim is twofold: First, we rigorously analyse the generators of quantum-dynamical semigroups of thermodynamic processes. We characterise a wide class of GKSL-generators for quan…
