超距作用和量子纠缠（量子纠缠距离超光速）

实验设计本身很值得一赞。

不过，它的结论（局域性隐变量理论无法完全重现量子力学的实验预言）是已经被其他实验检验过多次，基本被大家接受的。正如前面答主所说，其意义恐怕只在于补漏洞而已。

而Bell不等式检验实验的所谓漏洞几乎总是可以找到的，如果足够吹毛求疵。

例如Gerald tHooft肯定还是会提议大家考虑超决定论（

Superdetermini ***

）的思想，认为量子力学背后还是有一个确定性的局域隐变量理论（见

Loopholes in Bell test experiments

）。对此，包括荷兰代尔夫特理工大学的这个“迄今为止最严格的实验”都毫无办法。关于自由设置探测器的漏洞难以填补这点，John Bell本人早已经意识到了。

There is a way to escape the inference of superluminal speeds and spooky action at a distance. But it involves absolute determini *** in the universe, the complete absence of free will. （有一种办法可以排除掉超距作用的存在，但是需要完全剥夺自由意志。）

Suppose the world is super-deterministic, with not just inanimate nature running on behind-the-scenes clockwork, but with our behavior, including our belief that we are free to choose to do one experiment rather than another, absolutely predetermined, including the "decision" by the experimenter to carry out one set of measurements rather than another, the difficulty disappears. （假如宇宙是超决定论的，连实验者本身选择测量什么都是预定调和的话，困难就不攻自破了。）

There is no need for a faster than light signal to tell particle A what measurement has been carried out on particle B, because the universe, including particle A, already "knows" what that measurement, and its outcome, will be.（于是就不再需要超光速信号去向A粒子传达B粒子被如何测量，因为包含A粒子在内的宇宙本身已经事先“知道”会测量什么，其会得到的结果也是预定的。）
