Hybrid photon blockade with hyperradiance in a two-qubit cavity QED system
Abstract:
We investigate a hybrid photon blockade (HPB) scheme in a driven two-qubit cavity QED system arising from the combination of eigenenergy-level anharmonicity (ELA) and quantum destructive interference (QDI). By tuning the qubit and drive detunings, we identify parameter regimes that combine the brightness of ELA-based conventional photon blockade with the strong antibunching of QDI-based unconventional photon blockade. Interestingly, these regimes are accompanied by hyperradiance, indicating that inter-emitter correlations give rise to enhanced collective emission. The HPB mechanism retains parametric generality under coupling asymmetry and is accessible through detuning control, offering a feasible route toward high-quality single-photon sources.
