Quantum communication might be possible?

This interesting thought experiment is based on the classical double
slit experiment.

First you record (without observing) the which-way information of each
particle at the slits, and the particle landing point information at
the back wall separately. You store the information in two separate
memory storages, after which you move the second memory storage far
away from the first one.

Then you make a delayed choice about erasing or not touching the
which-way information recorded at the slits particle by particle and
stored in the first memory storage. This will "affect" the landing
point information (of the respective particles) recorded at the back
wall and delivered over a long distance as the second memory storage.
In other words, you have quantum communication, do you?

Well, we need more details. See the full description at

Why wouldn't it work? I have briefly discussed this with a couple of
qualified experts, and they couldn't say why it wouldn't work, although
they believe that there must be something wrong with the idea. It might
be so.

I don't know. I'm not claiming anything here, just wondering. What do
you think?
