Paper Abstract

As an important resource of the quantum information engineering, to explore its' possible applications and limits in the field of the secure communication is very necessary. In the paper we analyse the problem of the security of quantum secret sharing with Smolin bound entangled states as the channel quantum state. An intercept-resend strategy of the inner of the legal communicators is proposed to attack the security without be detected by the checking procedure with comparing the results of single-qubit measurement. A conclusion that quantum secret sharing only with Smolin bound entangled states as the channel quantum state isnot unconditionally secure is attained, and a general proof in terms of the quantum correlation is given.
