Examples
-
Penrose and Stuart Hameroff have speculated that human consciousness is the result of quantum gravity effects in microtubules, which they dubbed Orch-OR (orchestrated objective reduction).
-
Decoherence must be avoided long enough for quantum computation to occur (and in Orch OR, for threshold to be reached by E = h/t).
-
And if you somehow manage to turn this into a discussion about Orch-OR, I won't hole you, but I will certainly make use of the eye-roll smiley.

That is the Penrose-Hameroff 'Orch OR' theory of consciousness as sequences of quantum computations inside brain neurons.
-
The two teamed up, with Hameroff showing how synaptic inputs could 'orchestrate' Penrose objective reductions in neuronal microtubules, hence 'orchestrated objective reduction' (Orch OR).

-
In Orch OR the essential quantum spacetime qualia of an observed object are reproduced in the brain, specifically in/around microtubules.
-
In 1998 twenty testable predictions of Orch OR were published, a number of which by 2007 had been validated, and none refuted.
-
The Penrose-Hameroff Orch-OR theory ( 'orchestrated objective reduction') proposes that microtubules perform not just molecular-scale computation, but also, specifically related to consciousness, quantum computations.
