A Note on Invariants and Entanglements

Quantum Physics 2009-11-07 v1 Condensed Matter High Energy Physics - Theory

Abstract

The quantum entanglements are studied in terms of the invariants under local unitary transformations. A generalized formula of concurrence for NN-dimensional quantum systems is presented. This generalized concurrence has potential applications in studying separability and calculating entanglement of formation for high dimensional mixed quantum states.
