Proof of the insecurity of quantum secret sharing based on the Smolin bound entangled states
Yu Ya-Fei, Zhi‐Ming Zhang · Chinese Physics B · 2009
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.
