If there was a form of consciousness that developed early on in the timeline of a universe, which processed information via quantum mechanics rather than the chemical impulses of lifeforms we're familiar with - what might the structure of these beings look like?
Further clarification: I'm looking for some kind of matter that might act like a medium for something analogous to brainwaves/neural oscillations, while also being much much simpler than organic life as we know it. The Boltzman brain suggestion is in the vein of what I want but it doesn't specify the physical aspect in any useful way.
