teleportation

Interesting slashdot story

one of comments says:

A pair of photons in the same state, on the other hand, are indistinguishable.

how can we be sure of that? maybe there is some property that is not the same, well at least their position heh..

aha, it also says here: http://en.wikipedia.org/wiki/Bell%27s_Theorem

The standard assumption in Quantum Optics is that "all photons of given frequency, direction and polarization are identical"

I was wrong.

hm, if they are in different locations, then electrical/magnetic/gravity field in their coordinates (of ALL other particles in universe) is probably different, so doesn't that affect their state? (so that it is different too)
