Coherent Quantum Feedback with Time Delays

Explore a 46-minute conference talk delivered at the New Perspectives in Many-body Physics with Quantum Optical Systems conference, where Hannes Pichler from IQOQI discusses coherent quantum feedback systems with time delays. Presented at the Kavli Institute for Theoretical Physics (KITP) in Santa Barbara, CA, the lecture contributes to a broader discussion on quantum interactions between atoms and light across various experimental platforms. Delve into complex topics including dense atomic media, ordered arrays, disordered ensembles, nanophotonic interfaces, and quantum electrodynamical circuits coupled to superconducting qubits. Learn about emerging challenges in atom-light interfaces, engineered light dispersion relations, reduced system dimensionality, and non-perturbative multiple light scattering. Part of a conference bringing together diverse researchers to exchange cutting-edge developments and identify future opportunities in quantum optical systems, with particular focus on experimental capabilities and cross-disciplinary applications in fields such as Rydberg atom arrays, ultracold molecules, and superconducting qubits for quantum computing.
