Does something travel FTL in Quantum Teleportation?

[mercury]

I'm somewhat unclear about Quantum Teleportation.

I think that there is a distant and instant change in the quantum
state (QS) in the teleportation scheme on bob 's particle
(polarization or spin) . There is no need Bob to receive signals and
to understand that there is a change. There is no need of Bob at all
in order to change the QS of the 2 particle in the EPR pair.

So I was asked - how do you verify that experimentally?

I am not a specialist in QT but I think there is experimental
prove!!!!!

Bob can measure (if he is there and wants to =96 this of course is not
necessary) his particle after the measurement proceeded by Alice but
much before the classical light signal arrives to his end. After
receiving the information (arrival of the light signal from Alice
about her results) he will convince himself (in 75%) that something
happened at the other end at the time Alice made her measurement and
this has an immediate effect on his particle. So we must conclude
that there is possible that "something" travels immediately.

One can not say that this something travels together with the light
signal.

So the question is does something travel (in the sense of happens)
instantly (FTL) or the change in Bob's particle follows after t=3DL/c.
Note that I don't insist that this can be used for communication
between Alice and Bob.
