Re: Has FTL communication really never been tested in this way?

"PostReplies":
Here's another page I found explaining
his experiment and a very interesting
earlier experiment which was encouraging:
http://www.paulfriedlander.com/text/timetravel/experiment.htm

There is an interesting quote,
about Dopfer experiment, from that link.

"The important conclusion is that,
while individual events just happen,
their physical interpretation
in terms of wave or particle
might depend on the future"
[A.Zeilinger]

Now it seems to me that the key word
is "interpretation". Meaning that
from a *single* spot, on the two-slit
screen, produced by one photon passing
through the interferometer, one cannot
realize if that *single* spot is part
of an inteferential pattern *or* part of
a smooth pattern. One can realize precidely
that only after he measures, in the future,
the position *or* the momentum of the other
photon entangled with the first one.

(The third possibility, that one doesn't measure,
in the future, the position or the momentum of
the entangled photon is interesting but it is not
relevant here).

But the problem I see (since long time) is this.
Imagine there is not a *single* spot (produced
by one photon) on the two-slit screen, but 1000
distinct spots (produced by 1000 distinct photons).
Can we still say that nobody can realize whether
these 1000 spots form an interferential pattern *or*
a smooth pattern, untill one measures,
in the future, the position *or* the momentum
of all the other distinct 1000 photons, each one
of them entangled with a photon producing the spot?
