After teleportation there are two 'me's, one ateither location. That effects the probabilities, surely?Mainly because it makes "I" ambiguous. One answer would be theprobability of me being in Moscow is zero and the probability of mebeing in Washington is zero, because I am going to be destroyed.Another answer would be the probability of me being in Moscow isone and the probability of me being in Washington is one, becausethere are going to be two of me.Surely this is directly analogous to the situation in the MWI.The only difference I can see is that in MWI the whole world splits,and by this I mean that in each branch your body maintains all thequantum entanglements. In the teleporter it is only the classicalstructure of you that can be duplicated (no cloning) and so all theentanglements are not duplicated (which why you can end up in twoclassically different places). Of course that all depends onassuming MWI is true. Sometimes I think it is a little ironic thatthe advocates of MWI reduce everything to computation/information -but they reject the Bayesian/epistemic interpretation of QM in orderto support it.

BrentIf I measure a quantum event like a photon bouncing off / through asemi-silvered mirror, the chances of each result is 50%. In"classic" qnautum theory I say there is a 50% chance of seeing thephoton reflect, say. In the MWI I do the same, but I am now awarethat the probabilities work out as they do because I'm duplicatedin the process (or two pre-existing but fungible versions of mehave now become distinct - or perhaps 2 lots of infinite numbers ofcopies...)Ignoring the teleporter and just looking at the MWI gives the sameresults but is perhaps a bit more intuitive. In the MWI "I" am alsodestroyed from moment to moment (or even in classical single-universe physics, if you attach me to a "brain state" it all getsvery Heraclitean), and/or I am also duplicated from moment tomoment (at least).But the probabilities still work - I have a 50-50 chance of seeingthe photon bouncing or transmitting, and equivalently I have a50-50 chance to end up in Moscow or Washington. It just seems lessobvious when I'm the particle in the experiment.--You received this message because you are subscribed to the GoogleGroups "Everything List" group.To unsubscribe from this group and stop receiving emails from it,send an email to everything-list+unsubscr...@googlegroups.com.To post to this group, send email to everything-l...@googlegroups.com.Visit this group at http://groups.google.com/group/everything-list.
