TOPIC: Quantum control of open quantum systems: from dissipation-protected to dissipation-driven quantum dynamics

Abstract
Precisely controlling the dynamics of real-world open quantum systems is a central challenge across quantum science and technology, woth implications ranging from quantum physics and chemistry to fault-tolerant quantum information processing. While overcoming the effect of uncontrolled decoherence and dissipation mechanisms is essential to meet this challenge, engineering the coupling to a dissipative environment can likewise be instrumental to a number of quantum control tasks. In this talk, I will describe recent advances in pursuing these two complementary approaches. In particular, I will focus on two representative problems: designing dynamically corrected quantum gates that simultaneously compensate for non-Markovian decoherence and control errors in spin qubits; designing Markovian dissipation that drives a many-qubit system to a target entangled state while respecting physical locality constraints.
