Operator Weighted Concurrence Measure on Two-Qubit Quantum System

Graphical Abstract

Abstract

Abstract

Based on the operator theory in Hilbert space, the definition of operator weighted concurrence entanglement measure was introduced by means of a reduced matrix of quantum states. The efficiency in identifying the entanglement of a quantum state was also analyzed. Together with some properties, the relation and consistency between the measure and quantum channels was studied in the meantime.
