论文摘要
半Quantum密码学涉及至少一名本质上是半量子或“古典”的用户。这样的用户只能以非常有限的方式与量子通道进行交互。已经开发了许多半量子密钥分配协议，有些具有严格的安全证明。据我们所知，在这里，我们首次显示量子随机数在半量子设置中可能产生。我们还开发了严格的安全性证明，从协议的随机比特生成速率限制为通道中的噪声函数。我们的协议和证明可能广泛适用于其他量子和半量子加密方案，在这些方案中，用户的功能受到限制。
Semi-quantum cryptography involves at least one user who is semi-quantum or "classical" in nature. Such a user can only interact with the quantum channel in a very restricted way. Many semi-quantum key distribution protocols have been developed, some with rigorous proofs of security. Here we show for the first time, to our knowledge, that quantum random number generation is possible in the semi-quantum setting. We also develop a rigorous proof of security, deriving a bound on the random bit generation rate of the protocol as a function of noise in the channel. Our protocol and proof may be broadly applicable to other quantum and semi-quantum cryptographic scenarios where users are limited in their capabilities.
