Ok, I'll be a little more discrete about the model.
If we can find something in the universe that isn't 'physical' in the same sense atoms are, can we build something with it? That sounds impossible - how can you 'build' anything out of something 'non-physical', like time?

Well, it turns out there is something we've found that looks a lot like something 'unphysical' but which is a connection between physical things - entanglement.

If we can build a model that "holds together" (preserves entanglement), can we use it to build arbitrarily complex switching networks - realise a logic of states, an algebraic surface?

"channels with memory" exist - since particles 'remember' entangled states; the memories can be erased by thermodynamic interference effects, so that's a big design problem. These channels don't 'store' anything physical however; and they're all one-way, simplex channels.
That is, the 'storage' is the connection itself; just as a photon connects (masslessly) two charged particles. The latter takes 'time' , whereas massless entanglement is time-independent, and so distance-independent. It depends (the signal does) on the thermodynamic noise level in the 'channel'.

Where do we go from here, bearing in mind we can 'use' entangled states already - up to a thermodynamic limit and a 'complexity limit' of 3-bit entangled GHZ states?
