Entangled photons.
Do entangled photons actually provide for information transfer faster
than the speed of light? I used to think so, but was persuaded by
discussion on this list that they do not.
The collapse of the entanglement goes faster than light (it may be
instantaneous). That is not disputed.
Unfortunately, the argument, as I remember it, is that that you can
only measure the direction (say) of a photon after its collapse. It
could be `up' (i.e., an arbitrary direction) or down (i.e., another
arbitrary direction, but 180 degrees in the opposite direction). You
cannot predict ahead of time which photons are `up' and which are
`down', so you cannot convey a message.
I know that entangled photons are a science fiction trope and rather
hope they can be used to transfer information faster than light.
But I don't know how.
I would love to be shown wrong.
