Entropic Inequalities for a Class of Quantum Secret Sharing States
entropic inequalities monotone span programs quantum secret sharing stabilizer states von Neumann entropy
2010/10/18
It is well-known that von Neumann entropy is nonmonotonic unlike Shannon entropy (which is
monotonically nondecreasing). Consequently, it is difficult to relate the entropies of the subsystems of a g...

In this article we present a general security strategy for quantum secret sharing (QSS) protocols based on the HBB scheme presented by Hillery, Buˇzek and Berthiaume [Phys. Rev A 59, 1829 (1999)]. We ...

Quantum secret sharing for general access structures
Quantum secret sharing general access structures
2010/10/15
We explore the conversion of classical secret-sharing schemes to quantum ones, and how this can be used to give efficient qss schemes for general adversary structures. Our first result is that quantum...
