电子合同是通过电子方式签订的合同，广泛应用于电子商务活动中。近年来，随着量子密码技术的快速发展，量子电子合约得到了研究者的广泛研究。在量子力学基本原理的支持下，本文提出了一种基于单光子的量子电子合约方案。在该方案中，双方签署同一合同的两份副本，然后将每份合同的副本发送给受信任的第三方。受信任的第三方验证双方的签名并比较签名副本以确定合同是否有效。与之前的方案相比，该方案基于单光子签署的量子电子契约。由于单光子易于制备和操作，因此该方案简单易实现。同时，该方案不需要双方交换签名，降低了通信的复杂度。尽管如此，它还是要求双方和第三方诚实守信。
An electronic contract is a contract signed by electronic means, which is widely used in electronic commerce activities. In recent years, with the rapid development of quantum cryptography technology, the quantum electronic contract has been widely studied by researchers. Supported by the basic principles of quantum mechanics, a quantum electronic contract scheme based on the single photon is proposed in this paper. In this scheme, two copies of the same contract are signed by both parties involved, and then a copy of each contract is sent to a trusted third party. The trusted third party verifies the signatures of both parties and compares the signed copies to determine whether the contract is valid. Compared with the previous scheme, this scheme is based on the quantum electronic contract signed by the single photon. Because the single photon is easy to prepare and operate, this scheme is simple and easy to implement. At the same time, the scheme does not need to exchange signatures between the two parties, which reduces the complexity of communication. Nevertheless, it requires both parties and the third party to be honest and trustworthy.
