Tuning individual atomic detunings and drive phase in a two-atom cavity-QED system simultaneously suppresses one- and three-photon backgrounds while enhancing two-photon output, and also enables correlated fluorescence photon pairs.
The work extends a prior protocol to compare single-click and double-click entanglement generation between ions over hundreds of kilometers, showing that optimal choice depends on phase stability and interface efficiencies.
