Dynamics and Control of Open Quantum Systems

Precisely characterizing and controlling the states and dynamics of realistic open quantum systems is a fundamental challenge across quantum science and engineering, and a prerequisite for harnessing the potential of quantum information processing. We are investigating a range of problems in quantum control from both a general system-theoretic perspective as well as in collaboration with experimentalists working on trapped-ion and solid-state qubit implementations. Current projects include dynamical decoherence suppression and noise identification in multi-qubit systems, quantum control using engineered dissipation, and fundamental limits to cooling.
