Researchers Demonstrate Strong Coupling via Dark State Resonances in Coupled-Cavity Quantum Electrodynamics System

Researchers Demonstrate Strong Coupling via Dark State Resonances in Coupled-Cavity Quantum Electrodynamics System

Coherent light-matter interaction at the single photon level is a long-standing goal for quantum operations. To reach such strong coupling regime, previous studies mainly focus on improving the quality (Q) factor and reducing the mode volume (V) of the same optical resonators, but they have already reached their limits due to current fabrication and other technological restrictions.
