Abstract
The quantum entanglements are studied in terms of the invariants under local unitary transformations. A generalized formula of concurrence for -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.
