Quantum Resonator as a Directional Quantum Emitter
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.A single‐photon source based on a two‐photon Jaynes–Cummings system features a resonator acting as the quantum emitter rather than the two‐level system. In this configuration, enhanced efficiency, purity, and indistinguishability are achieved, while robustness against dephasing, reduced energy dissipation, and broader implementation prospects for ...
