"Controlling Open Quantum Systems: From Dissipation-Protected to Dissipation-Driven Quantum Engineering."

"Precisely controlling the dynamics of real-world open quantum systems is a central challenge across quantum science and technology, with implications ranging from quantum to condensed-matter physics and 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 applications, notably open-system quantum simulators. In this talk, I will describe recent advances in pursuing these two complementary approaches. In particular, I will focus on two representative problems: using dynamical decoupling methods for non-Markovian error suppression to achieve high-fidelity quantum memory for long times, while minimizing access latency and sequencing complexity; and designing Markovian dissipative dynamics to drive a many-qubit system to an entangled steady-state of interest, while respecting physical locality constraints."
