Separability of Pure States and Mixed States of the Quantum Network of Two Nodes

GUZhi-Yu, QIANShang-Wu

Published Jan 1, 2003• 0 citations
OpenAlex

Abstract

This article discusses the separability of the pure states and mixed states of the quantum network of twonodes by means of the criterion of no entanglement in terms of the covariance correlation tensor in quantum networktheory, i.e. for a composite system consisting of two nodes. The covariance correlation tensor Mjk(1, 2) is equal to zerofor all possible j and k.
