Limited resource semiquantum secret sharing

Abstract

The idea of semiquantum secret sharing (SQSS) is that quantum Alice wants to share secret information with clients such as Bob and Charlie who have limited quantum capability. Neither Bob nor Charlie can reconstruct the secret information unless they collaborate together. In existing semiquantum secret sharing protocols, clients generally need the ability of quantum measurement in classical basis and quantum parties usually need to access quantum memory. In this paper, we propose a relatively efficient SQSS protocol where limited Bob and Charlie can realize secret sharing without making any measurements and quantum Alice does not have to access quantum memory.
