| Abstract: | The notions of D-computable state and D-concurrence are generalized to the C M ⊗ C N system. A class of D-computable state on C M ⊗ C N is given and the calculating method of the lower bound of D-concurrence is provided. The obvious expression of the lower bound of D-concurrence for the state mixed by two D-pure states is derived.
