Fig. 2: Experimental results of the correlated two-photon states.

a Coincidence count rate versus pump power; The insert figure is coincidence histogram of the signal and idler photons at 1559.79 nm (C22) and 1559.79 nm (C46). b Single side count rate of the idler photon from 1559.79nm (C22) versus pump power. c CARs versus pump power. The lines are theoretically calculated by coincidence and single side count. The error bars of the CAR are obtained by Poissonian photon-counting statistics of coincidence count and background noise fluctuation.
