A Quantum of Consciousness

Broadly speaking, suggestions about the mechanisms that might cause consciousness can be grouped into three: (i) the vital spark of life, (ii) an emergent property from basic control functions of the central nervous system and (iii) a special relationship between spooky quantum interactions and life.

But repeated experiments have shown that electron transfer in photosynthesis has an efficiency greater than ninety-nine percent, probably because of superposition and electron tunnelling.

And evidence is gathering that many enzymes may use spookiness for electron transfer. Enzymes are the classic controlling agents for the body’s biochemistry: the hierarchy is that DNA makes RNA makes enzymes, which then go on to regulate everything else. Many other biological systems are currently being investigated for quantum influences such as vision, olfaction, magnetoreception (detecting magnetic fields) and Brownian motors (typically nano-scale engines in a cell that convert chemical into mechanical energy)."

"Maybe, just maybe, consciousness is an emergent property of the positive and negative feedbacks between quantum mechanics effects at the level of single ions and an overarching electromagnetic field around the brain."

"To conclude we have no evidence that consciousness and self-awareness are caused by the number of links in a digital system."
