Oral: Creating Artificial Quantum Reservoirs through Driven-Dissipative Processes in Superconducting Circuits

Energy dissipation and dephasing are commonly perceived to be detrimental to quantum information processing. However engineering driven-dissipation offers new possibilities to prepare, control and probe many-body quantum states, and can be a powerful tool to help understand the effect of environmental couplings in analog quantum simulators. In this context, we develop a superconducting circuit lattice experiment with tunable local baths, and utilize the driven-dissipative processes between superconducting qubits and their readout resonators to prepare and stabilize single- and multi- qubit states. These quantum states can serve as artificial quantum reservoirs with controllable chemical potential or temperature. We discuss plans to apply these controlled artificial reservoirs to study the dynamics of many-body systems in our open-system quantum simulator, and for quantum thermodynamics and implementing quantum heat engines.
