摘要：

We comprehensively investigate the local distinguishability of orthogonal Dicke states under local operations and classical communication (LOCC) from both qualitative and quantitative aspects. Based on our work, defects in the LOCC-quantum secret sharing (QSS) scheme can be complemented, and the information leakage can be quantified. For (k1, k2, k, n)-threshold LOCC-QSS scheme, more intuitive formulas for unambiguous probability and guessing probability were established, which can be used for determining the parameter k1 and k2 directly.
