Interfacing Spins with Photons for Quantum Simulation and Quantum Control

Monika Schleier-Smith

Coupling many atoms to a single mode of light offers an efficient means of spreading quantum information across an extended many-body system.  In ongoing experiments, we are harnessing photons in an optical cavity to mediate flip-flop interactions among distant spins in a cloud of rubidium atoms.  Such interactions can enable quantum simulations of exotic Hamiltonians featuring non-local hopping of strongly interacting bosons, which may ultimately shed light on fundamental bounds in quantum information scrambling.  I will also touch on complementary prospects in cavity-aided quantum control, focusing on a robust and versatile scheme for “painting” non-classical collective spin states using a single photon as a “brush”.
