标题： Random 'choices' and the locality loophole

摘要： 已经有人声称，在贝尔实验中关闭局域性漏洞，应该使用量子起源的随机数来选择测量设置。 这是在所有最近针对这一漏洞的贝尔实验中所采用的方法。 本文指出，此类实验并不需要量子随机数生成器，使用伪随机（但 otherwise 完全确定性）的机制来选择测量设置的贝尔实验，例如对最新一百万条带有#quantum标签的推文进行哈希函数处理，将同样具有说服力，甚至可能比使用量子随机数生成器的实验更具说服力。 显示英文摘要

摘要： It has been claimed that to close the locality loophole in a Bell experiment, random numbers of quantum origin should be used for selecting the measurement settings. This is how it has been implemented in all recent Bell experiment addressing this loophole. I point out in this note that quantum random number generators are unnecessary for such experiments and that a Bell experiment with a pseudo-random (but otherwise completely deterministic) mechanism for selecting the measurement settings, such as taking a hash function of the latest million tweets with the hashtag #quantum, would be as convincing, or even more, than one using quantum random number generators.
