Welcome to the Quantum Inspired Coherence Optics Research Group at Stevens
Our group focuses on theoretical and experimental research of various intrinsic links between quantum and classical. We explore properties such as entanglement, coherence, Bell violation, wave-particle duality, etc., that are widely considered as uniquely quantum, in the context of classical optical fields; We study theory of multiparty quantum information including coherence/entanglement sharing, measure of multiparty coherence/entanglement, quantum multi-tasking, quantum state/coherence transfer, etc. We also investigate various quantum optics and quantum foudnational issues such as spontaneous emission, single photon coherence, cavity QED, quantum duality. Our group also studies emerging field of magnonics stimulated by strong magnon-cavity interaction.
