What is the basis of quantum teleportation?
« on: 25/08/2009 15:01:45 »
particles have a particle property and wave property, and the wave is actually the probability of finding a particle in a certain location
for some microscopic view, electrons really did transport themselves from one place to another without traveling. So i hv an interesting question, when we put a small object (not even a living things) on one end of an empty table, if we use a gigantic super computer compute all atoms of an small object, theoretically the probability of finding all atoms on the other end of the table is plausible, so is theoretically this kind of transportation is possible?

Kind of like, "Beam me up Scotty"? Maybe it's possible but I suspect it is not very likely that anyone alive today will survive to see it.

Why do you need the computer?  If you have an object on one end of the table, there is an infinitesimally small probability of it suddenly "appearing" on the other end, according to quantum mechanics.  But from what I've heard quoted, odds are that won't have happened yet, even in the current age of the universe.

I see a theoretical objection, to transport an object you would have to measure the type and position of every atom and reconstitute it in the new position it is of course not possible to measure the position and velocity of atoms simultaneously.

And could you be sure that there would be room for it at the other end of its journey? Where would you 'aim' it to avoid turning up 10m underground? A great SciFi story called Sundog discusses the problem of 'Jaunting' and imposes a limit to how far you can go. (No, really, I didn't actually believe it.)
