| Abstract: | This paper reconsiders carefully the possibility of using the
Smolin bound entangled states as the carrier for sharing quantum
secret. It finds that the process of quantum secret sharing based on
Smolin states has insecurity though the Smolin state was reported to
violate maximally the two-setting Bell-inequality. The general proof
is given. |
