已经证明，使用包含具有量子属性的组件的设备可以实现两个合作伙伴之间的安全通信。虽然这些器件还处于实际应用的胆小阶段，但所展示的量子特性在理论上是定义良好的：持久量子态中的量子比特(量子比特)，适用于量子比特的量子变换或门，以及设备之间的量子通信通道。本文通过仿真对不使用加/解密密钥的量子通信协议的安全级别进行了测量和验证。该算法比首先分发密钥的两步协议简单。我们的仿真根据以下几个参数来衡量协议的安全级别：编码基数(两个或三个)、附加在消息上的签名串的长度、窃听者检查的量子比特的百分比等。
It has been shown that secure communication between two partners can be achieved with devices containing components with quantum properties. While such devices are in timid stages of practical availability, the quantum properties exhibited are well defined theoretically: quantum bits (qubits) in persistent quantum states, quantum transformations or gates applicable on qubits, and quantum communication channels between devices. The present paper measures and verifies by simulation a security level of a quantum communication protocol that does not use an encryption/decryption key. The algorithm is simpler than the two-step protocols that involve the distribution of a secret key first. Our simulations measure the security level of the protocol depending on several parameters: the number of encoding bases (two or three), the length of the signature string attached to the message, the percentage of qubits the eavesdropper inspects, etc.
