摘要
Quantum secret sharing(QSS)schemes are analyzed from an information theoretical perspective centered on the Araki–Lieb inequality.Based on this inequality,mathematical characterizations of QSS schemes and quantum error-correcting codes(QECCs)are given.Furthermore,we present a proof of the relation between QSS schemes and QECCs.This information theoretic description of QSS schemes is used to derive the quantum Singleton bound.
