Semi-quantum secret sharing in high-dimensional quantum system using product states

To make the quantum secret sharing more practical, semi-quantum secret sharing protocols in two-dimensional quantum system have been extensively investigated. This paper proposed a novel semi-quantum secret sharing protocol in high-dimensional quantum system using product states. In the present protocol, the quantum capabilities of the receivers Bob and Charlie are limited, and all participants do not have to access quantum memory. Security analysis indicates that the present protocol is complete robustness to intercept-measure-resend attack and entangle measure attack. Comparisons between the present protocol and existing protocols are illustrated, which indicates that the present protocol is more efficient. Furthermore, the key rate in different quantum noisy channels is calculated.
