Research

Our research program advances neutral-atom and photonic quantum technologies through tightly integrated experimentation, theory, and system engineering. In quantum computing, we are building a high-performance single-atom array platform featuring Raman single-qubit gates, Rydberg-mediated two-qubit interactions, moving optical tweezers, flattop beam shaping, and background-free state detection. A second-generation QC system is under development to scale atom numbers, enhance stability, and open new directions in fast control and real-time feedback.

In quantum memory, we explore light–matter interactions in a record-high-OD cesium MOT to uncover superradiance, vacuum-induced quantum beats, and atomic lensing effects. These studies illuminate collective emission and propagation in dense media and form the foundation for an ultrabroadband, high-efficiency photon-storage interface.

Our photon-pair and entanglement research develops broadband SPDC sources in pp-KTP crystals, with ongoing characterization of correlations, purity, and generation rate. The goal is a memory-compatible single-photon interface suitable for quantum networking and high-bandwidth storage.

Across all projects, we emphasize integrated systems and automation—optics, electronics, FPGA/firmware, and software—that support stable, reproducible, and scalable experiments.
