Abstract

We explore the bipartite non-classical correlations of two quantum wells coupled to two spatially separated microcavities. The microcavities are filled by linear optical media and linked by a single-mode optical fiber. We prove that it is possible to generate a correlation from the initially uncorrelated state. With particular coupling constants of the cavity-exciton and the fiber-cavity coupling, the maximum correlations can be generated periodically, and sudden changes occur only in the local quantum uncertainty. The optical susceptibility and coupling constants control the regularity, amplitudes, and frequencies of the correlation functions. When the system initially starts with a maximally correlated state, we show that the correlation robustness of the Wigner-Yanase skew information and Bell’s inequality depends not only on the coupling strengths and optical susceptibility but also on the dissipation rates. Deterioration of the correlations is substantially associated with the dissipation.
