It has been achieved only with single particles .. and only in the sense that the entire information about the particle is teleported for 1 particle to another… to make that happen with anything bigger would we extremely difficult (and potentially dangerous!).. But not necessarily impossible
Well … as Jack said it was done with simple information being transported from one particle to another but not physically the whole particle … so from this, the question is? Will information transfer be enough and is creating another object that has all the details of the original one called teleporting?! I believe it would be if the replica is exactly a copy of the original and lacks nothing in details or complex structure so I can see it a possibility in the near future!!
