Limited Resource Semi-Quantum Secret Sharing Based on Multi-Level Systems

摘要

In the actual quantum task, it is more realistic to achieve the same task with quantum resources as few as possible which is known as semi-quantum idea. This paper proposed a novel and resultful semi-quantum secret sharing protocol, which is implemented using product states based on multi-level systems. In this scheme, the quantum capabilities of the receivers Bob and Charlie are limited, and the sender Alice does not have to access quantum memory. In addition, the security of the protocol is analyzed in detail from two aspects of Intercept-measure-resend and Entangle-measuring attacks initiated by internal malicious participants. More importantly, among the premise of proximate security of Ref. Li et al. (Quantum Inf. Process. 17, 285, 2018), our scheme reduces the number of particles used for eavesdropping detection and increases the amount of information carried by each particle.
