摘要：

Based on the fact that there is no secure E-payment system for direct transactions between banks, an improved inter-bank quantum E-payment system has been built. By taking advantage of good entanglement properties of the four-particle Cluster state and the unique measurement rules, our system cannot only support the unconditional security of E-payment, but also guarantee the blindness of the purchase information. Besides, our system also satisfies the properties of undeniability and unforgeability.
