Watch a 42-minute conference talk from the New Perspectives in Many-body Physics with Quantum Optical Systems conference where Sarang Gopalakrishnan from Princeton explores gaps of local quantum channels in the weak-dissipation limit. Delivered at the Kavli Institute for Theoretical Physics (KITP) in Santa Barbara, the presentation is part of a broader conference examining quantum interactions between atoms and light across various experimental platforms including dense atomic media, nanophotonic interfaces, and quantum electrodynamical circuits. Learn about the complexities arising from engineered light dispersion, reduced system dimensionality, and non-perturbative multiple light scattering in these cutting-edge quantum optical systems. Gain insights from this gathering of diverse researchers discussing state-of-the-art developments and future challenges in fields spanning Rydberg atom arrays, ultracold molecules, and superconducting qubits for quantum computing.
