量子随机数发生器（QRNG）是一类量子密码协议，可从量子源提取出安全的随机比特串。该领域的主要研究挑战之一是提高其随机比特生成速率。在此，我们探究了针对QRNG协议的几种可能的后处理策略，阐明它们何时有益、何时有害。我们还审视了使用这些方法时的权衡取舍，因为其中一些方法需要大量的初始随机性。最后，我们对一些有待解决的有趣未来问题进行了评述。
Quantum Random Number Generators (QRNG) are quantum cryptographic protocols that distill secure random bit strings from quantum sources. One of the main research challenges in this area is to improve their random bit generation rates. Here we investigate several possible post processing strategies for QRNG protocols, showing when they help and when they hinder. We also look at the trade-offs to using these methods as some require a larger amount of initial randomness. Finally, we comment on some interesting future problems that remain open.
