The Optimal Information Rate of Quantum-Secret-Sharing Schemes Based on at Most Four Participants
The information rate is an important metric of the performance of a quantum-secret-sharing scheme.In this paper
we characterize the quantum access structures by means of the theory of hypergraph.Furthermore
we derive the optimal information rate and the construction of perfect quantum-secret-sharing schemes corresponding to the quantum access structures with at most four players which are given in terms of the relationship between certain access structures and hypergraphs.The exact values for the optimal information rate in 5 of the 13 access structures are computed and the relevant construction of perfect secret sharing schemes is discussed.At the same time
the upper bounds for the information rate of other 8 quantum access structures are computed.
