WebJul 1, 2024 · Introduction. Nowadays, researchers are showing the great interest in photonic spin Hall effect (PSHE) to control the flow of light [1,2], to see the spin and orbit angular momentum interaction [3], to identify the number of layer numbers in 2D materials [4], to design an optical device [5], in communication [6], and chemical and biological sensing [7,8]. WebSpin-photon coupling has been studied but is challenging because of the small magnetic-dipole moment of a single spin, which limits magnetic-dipole coupling rates to less than 1 kilohertz. Thus, there is a need for more sophisticated techniques for establishing quantum information systems.
