摘要

Quantum visual secret sharing is a novel and important research direction. It has higher security and practicality. However, current schemes are designed for the sharing and recovery of a single secret image. To address this problem, we propose a novel (2,2) quantum visual multi-secret sharing (QVMSS) scheme. In the sharing phase, a quantum encoding table is designed. The colors of the two secret images are entangled and encoded into four different quantum superposition states, which are then distributed to the participants. All secret images are recovered using quantum OR operation and quantum shift operation in the recovery phase. We conducted experiments on a set of 20 standard halftone images to test the feasibility of our proposed scheme. Our scheme can completely recover all the secrets while improving the efficiency and security compared to traditional schemes.
