Abstract: In this paper, some non-classical correlations are investigated for bipartite partitions of two qubits trapped in two spatially separated cavities connected by an optical fiber. The results show that the trace distance discord and Bell’s… read more here.

Abstract: The pairwise nonclassical correlations for two-qubit states, extracted from multi-qubit system with exchange symmetry and parity, are quantified by local quantum uncertainty and trace distance discord. The explicit expressions of local quantum uncertainty and geometric… read more here.
