摘要:

We investigate the performances of the pairwise correlations (PCs) in different quantum networks consisting of four-wave mixers (FWMs) and beamsplitters (BSs). PCs with quantum correlation in different quantum networks can be verified by calculating the degree of relative intensity squeezing for any pair of all the output fields. More interestingly, the quantum correlation recovery and enhancement are present in the FWM+BS network and the repulsion effect phenomena (signal (idler)–frequency mode cannot be quantum correlated with the other two idler (signal)–frequency modes simultaneously) between the PCs with quantum correlation are predicted in the FWM+FWM and FWM+FWM+FWM networks. Our results presented here pave the way for the manipulation of the quantum correlation in quantum networks.
