a, Second-order cross-correlation of the RF photons detected from output G3 and G4 when M1 and M2 are resonantly driven at the excitation level of S = 0.5. The red trace is the theoretical curve for the ideal situation where the emitters have no pure dephasing and the detection is perfect (without background and dark counts). The cross-correlation curve exhibits a pronounced beating feature with a period of 2.5 ns, in accordance with the 400 MHz frequency detuning between the molecules. b, Same as a but for long time delays around 100 µs.
