Quantum Information Splitting of Arbitrary Two-Qubit State Via a Five-Qubit Cluster State and a Bell-State

We propose a scheme for Quantum Information Splitting of Arbitrary Two-qubit State via a Five-qubit Cluster State and a Bell-state as the quantum channels. There exist a sender (Alice) and two receivers (Bob and Charlie), who share a seven-qubit cluster state as the quantum channel. Alice performs a Bell-state measurements (BSMs) on her qubit pairs, Alice reveals the results to Bob and Charlie via a classical channel. If it is impossible without the help from Charlie for Bob to reconstruct the original information. Charlie performs GHZ-state measurements on his particles and informs Bob about the result. Bob will perform unitary operations to reconstruct the original state information. This scheme is tested for different eavesdropping attacks, of which eavesdropping is easy to detect. In addition, we compared the agreement, such as the number of particles in the program itself, the method of measurement and the efficiency of measurement, etc. All of those prove the innovation of the comprehensive measurement method in this experiment. Overall, we can get the conclusion from the comparison that the scheme is more stable and robust in terms of transmission efficiency and security.
