【龙腾网】有关黑暗森林理论的讨论，可怕的科学理论(9)
这个世界已经在进行量子通信的实验。在早期阶段，是这样的，但是如果有先进的文明存在，很有可能他们已经知道如何做到这一点，并且停止使用我们现在仍在使用的无线电通讯。
Roger Phelps
Quantum communications do not evade the speed of light limit. You may have heard that measuring some property of one of a pair of entangled particles instantly fixes that property for the other member of the pair. That is true but since the properties are indeterminate until the first measurement is made, the only information that the second measurement gives is the value of the property given by the first measurement. This is not a basis for faster than light communications.
量子通信无法规避光速的限制。您可能听说过，测量一对纠缠粒子中的一个的某些属性可以立即确定另一个的属性。这是正确的，但是由于这种属性在第一次度量之前是不确定的，所以第二次度量给出的惟一信息是第一次度量给出的属性的值。这不是比光通信更快的基础。
Roger Phelps
No. All that person A finds out is the results of person B’s measurements. By definition person B’s measurements are completely random and contain absolutely no information. Some very bright minds have examined this question and have come to the conclusion that this is not a basis for FTL communication.
不。A只知道B的测量结果。根据定义，B的测量完全是随机的，不包含任何信息。一些非常聪明的人研究过这个问题，并得出结论，这不是超光速通信的基础。

If it were possible to violate these laws you’d expect, in the vast expanse of even just the visible universe, to see plenty of evidence of that happening.
