Quantum Correlation Swapping between Two Werner States Undergoing Local and Nonlocal Unitary Operations

Blog Article

In this read more paper, quantum correlation (QC) swapping between two Werner-like states, which are transformed from Werner states undergoing local and nonlocal unitary operations, are studied.Bell states measures are performed in the middle node to realize the QC swapping and correspondingly final correlated sates are obtained.Two different QC quantifiers, i.

e., measurement-induced disturbance (MID) and ameliorated MID, are employed to characterize and quantify all the concerned QCs in the swapping process.All QCs in the concerned states are evaluated analytically and numerically.

Correspondingly, their characteristics and properties are exposed in detail.It is exposed that, through the QC swapping process, one can obtain the long-distance QC indeed.Moreover, the similarities of monotony features of MID and AMID between the initial states sukin body lotion woolworths and final states are exposed and analyzed.
