Our research group focuses on both the theoretical and experimental exploration of fundamental quantum-classical connections and its application in optical systems. We investigate foundational properties such as wave-particle duality, Bell inequality, entanglement, and coherence that exist in both quantum and classical systems. A key aspect of our research involves simulating quantum system beahviors and quantum information and computation tasks using classical coherence optics based on these analogies. To further our understanding of quantum-classical connections, we also delve into open system quantum phenomena including decoherence, disentanglement, Purcell effect, etc., within cavity QED and cavity magnonic systems.
