Many-Body Dynamics in Driven-Dissipative Superconducting Quantum Circuits

Explore groundbreaking research in quantum physics through this technical talk focusing on many-body dynamics in superconducting quantum circuits. Delve into recent experiments on quantum transport in superconducting circuit lattices, featuring a novel method for measuring in-situ particle current and current statistics. Learn about the coupling of 1D Bose-Hubbard lattice to engineered particle sources and drains, examining energy-dependent current in discrete conduction channels and interaction-assisted transport. Discover how engineered particle baths enable site-resolved tunneling spectroscopy for measuring quasi-hole and quasi-particle spectra and understanding collective lattice excitations. Gain insights into the application of coherent and driven-dissipative techniques for controlling complex quantum dynamics, and understand ongoing research efforts to generate novel entangled many-body states in circuit-based quantum simulators. Presented by Dr. Alex Ruichao Ma, an NSF CAREER Award recipient and Assistant Professor at Purdue University's Department of Physics and Astronomy, whose expertise spans ultracold atoms, superconducting qubits, and quantum simulation.
