摘要：
Entanglement of formation for a class of higher-dimensional quantum mixed states is studied in terms of a generalized formula of concurrence for N-dimensional quantum systems. As applications, the entanglement of formation for a class of 16 x 16 density matrices are calculated. (C) 2003 Elsevier Science B.V. All rights reserved.
