摘要：

We provide a supersymmetric generalization of n quantum bits by extending the local operations and classical communication entanglement equivalence group [SU(2)](n) to the supergroup [uOSp(1/2)](n) and the stochastic local operations and classical communication equivalence group [SL(2, C)](n) to the supergroup [OSp(1/2)](n). We introduce the appropriate supersymmetric generalizations of the conventional entanglement measures for the cases of n = 2 and n = 3. In particular, super-Greenberger-Horne-Zeilinger states are characterized by a nonvanishing superhyperdeterminant.
