PROGRAMMABLE QUANTUM SPIN DYNAMICS WITH TRAPPED ATOMS COUPLED TO A NANOPHOTONIC MICRORING RESONATOR
Abstract
Trapped atom quantum simulators have offered the major testbed for understandings of quantum many-body dynamics in paradigmatic models, which would describe either real world or idealized quantum materials. With recent advances in experimental techniques, a powerful designer quantum simulator with trapped atoms may be realized with pairwise programmable interactions, allowing one to obtain new insights on the dynamics of novel quantum materials with frustrated interactions, strong and long-range correlations, as well as non-trivial topology and boundary conditions. The proposed research aims at using a nanophotonic optical resonator for trapping atoms and hosting strong single atom-photon interactions, and for realizing pairwise-tunable interactions between trapped atoms mediated by resonator photons. Specific program objectives include- (1) quantum device development, where an ultrahigh quality microring resonator circuit will be developed as a high-fidelity atom-photon quantum interface and as a novel quantum simulator platform; (2) trapped atom array integration, where we will initialize laser-cooled atoms in an array of surface micro-traps and demonstrate programmable array initialization by employing site-resolved atom-microring coupling and fluorescence detection; (3) exploration of chiral atom-photon coupling that is controlled by tunable atom-microring system topology, and demonstration of tunable atom-atom interactions mediated by microring photons; and (4) quantum simulation of a topological Creutz ladder with programmable interaction in a trapped atom array, using which we will explore topology-related quantum quench dynamics, from periodic to open boundary conditions. Our research demands close integration of state-of-the-art ultracold atom physics, quantum optics, and nanophotonic technologies. This project would produce a chip-scale, scalable nanophotonic quantum interface integrated with trapped atoms, enabling wider applications in quantum information sciences and quantum technologies. This would enhance the AFOSR mission to foster fundamental research and scientific discoveries that would provide technological innovations for future applications.
