The idea's of Penrose, et al, regarding the nature of [quantum] consciousness is not generally taken seriously, except by a minority of 'quantum consciousness' enthusiasts.
Even assuming, for the sake of argument, that Penrose, et al, are right and that consciousness does indeed depend on - ''biologically “orchestrated” coherent quantum processes in collections of microtubules within brain neurons, that these quantum processes correlate with, and regulate, neuronal synaptic and membrane activity'' - this process is still not under conscious control or regulation by will. Consciousness is still remains whatever the brain is doing regardless of quantum mechanisms or classical mechanisms.
If the system of information processing breaks down, be it quantum or classical, this is reflected in conscious experience and no power of the will can alter the underlying conditions.
