Classical information, in the "physical" traditionnal sense has
always been considered as possible. Classical information is teleported
at evry moment through phones, nets, TV-channel, etc. In Science-Fiction
book, it has often been called simply "teleportation". Only with the advent
of "quantum teleportation" sometimes I feel the need to add "classical"
for preventing possible confusion.

I don't understand. If someone is Turing-emulable at level L, and if by
chance he/she bet on that level for comp practice, then he/she can send
his/her digital description made at that level through any classical
information channel. Of course if the level is very low, for example if
there is a need to encode the quantum state
of the whole cosmos, then it is not possible to do it in practice. But
the reasoning still follows. So if you accept Turing-emulablity at a level
(even if only for the sake of the argument), then I don't see how you 
could deny the possibility of classical teleportation at that level 
(even if only for the sake of the argument).

>PS. How far have you considered Chu transforms?

Still not very far. Thanks for pointing me to Vaughan Pratt paper btw.
The paper proves also that it is possible to be a logician and at the
same time be aware of the mind-body problem (reconforting idea). But
Pratt's conception of mind is to narrow for my purpose. Nor can I take
his dualism as an ontological dualism, so his stuff is no really
stuff, and his approach is best seen as a sort of still purely
mathematical monisme, even if his use of the Chu transform give a nice
dualist panorama. We will see. Today, among the logicians, I would say
the Blute-Girard linear functors seems more rich, respectively to the
goal of finding intermediate structures between Z1* (the comp physics)
and Quantum Mechanics.

Best Regards,
