But I don’t think it’s a good argument at all. Has the system M decohered and thus become entangled with M’ after M measures the spin? If so, then M and M’ are already on the same branch/ in the same world as one another and there is only one possible measurement M’ can make. The outcome is not subject to probability. If on the other hand, the system M has not decohered with the common environment of M’, then M remains in a superposition of up and down measurement states until measured by M’ and it does not make sense to say that either the electron or M itself are in a definite state with respect to M’. Both branches/ worlds exist and M’ has not yet split on the outcome. It’s a pretty basic point. > <https://link.springer.com/article/10.1007%2FBF00763476> > > -- > You received this message because you are subscribed to a topic in the > Google Groups "Everything List" group. > To unsubscribe from this topic, visit > https://groups.google.com/d/topic/everything-list/xsl8cSDT4M8/unsubscribe. > To unsubscribe from this group and all its topics, send an email to > [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/everything-list/53333396.1238733.1610788558703%40mail1.libero.it > <https://groups.google.com/d/msgid/everything-list/53333396.1238733.1610788558703%40mail1.libero.it?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
