Sun Group Research

Our group explores light-matter interactions at the fundamental quantum limit, where single atoms can strongly interact with single photons. We realize this capability by design and fabrication of nanophotonic structures that confine photons at an extremely small volume, which are then coupled to solid-state artificial atoms such as quantum dots and atomic defect centers. In addition to the interest of understanding fundamental physics through the generation of exotic light-matter interactions, we aim to apply the quantum light-matter interface for quantum information applications, including nonclassical light generation, entanglement distribution, and optical quantum information processing. We are also interested in developing new noise spectroscopy and quantum control techniques for applications in noise mitigation and quantum sensing.

Deterministic generation of nonclassical state of light

Our group aims to develop new schemes and devices for deterministic generation of nonclassical light based on cavity quantum electrodynamics (cavity QED).

Photon-mediated entanglement distribution and many-body interactions

Our research group is actively dedicated to developing novel schemes and devices specifically designed to enable efficient, rapid, and high-fidelity entanglement distribution and many-body interactions among solid-state spins.

Quantum control and noise spectroscopy

In this research endeavor, our primary objective is to develop new noise spectroscopy techniques that enables more accurate and efficient characterization of the frequency-dependent spin-environment coupling, and to develop advanced quantum control methodologies for better noise mitigation.
