You have to measure many particles, all prepared in the same way, and if they all come out the same way, then they must have been locked. But in the case of a particle whose entangled partner has been measured, some will be locked into state A, and others into state B. In principle, this is indistinguishable from the scenario where the entangled partner has not been measured; the probabilities must be identical.millerhttps://www.blogger.com/profile/05990852054891771988noreply@blogger.comtag:blogger.com,1999:blog-9124539381685751273.post-39361067964162822642012-06-14T08:12:21.564-07:002012-06-14T08:12:21.564-07:00I'm curious about something.

Is there any way that the knowledge THAT there's entanglement could be used to send a bit of data across long distances?<br /><br />From what I understand, the particulars of spin or whatever is entangled won't work for communication. In other words, reading "left" would be no different than reading "right" because there's no way to say how it was originally entangled. However, is there some means by which one can detect that the other hand has been measured at all? That should be enough to develop a basic communication system. If a reading at one end locks the other end, is there a way for that "locked" state to somehow START an interaction? So, the measuring device would just sit around waiting for that state to be set and ignore completely what it gets set to.<br /><br />If not, then never mind on that front, but it's something I've been curious about.Anonymousnoreply@blogger.com
