There is an "emerging field" called quantum biology, the existence of which suggests that there could be some connection between the quantum and biological worlds. WP also has article. Doesn't mean that there is any connection to mental states of course, but it would seem to mean that the idea shouldn't be rejected out of hand.Weirdstuff (talk) 17:38, 25 September 2012 (UTC)
- It wouldn't be dismissing it out of hand to say that (non-trivial) quantum effects probably aren't the source of consciousness. In the case of photosynthesis I'm struggling to see how the effect is being lumped in as "non-trivial" considering you're exploring photo-excited states, where obviously quantum effects will come into play because you're manipulating spins during those reactions. Spotting non-trivial quantum effects into the purely thermochemical world of neurology is something else entirely. pathetic 00:30, 27 September 2012 (UTC)
Quantum Computing, Decoherence and Woo
The idea that the mind functions as a quantum computer and thus tquantum mechanical phenomena are needed to explain consciousness is almost universally rejected by neuroscientists as well as physicists and theoretical computer scientists studying quantum computing on the grounds that neurons are simply too large and the brain too hot for quantum decoherence to make psychic phenomena explainable by anything more than classical physics. Quantum computing researcher Scott Aaronson has discussed this numerous times in his blog and in both academic and public talks (cf. https://www.youtube.com/watch?v=Z7lv4-Bah5c).
Discussions of exotic forms of physics as responsible for consciousness are rooted in unfalsifiable hypotheses.
Quantum biology is largely concerned with ab initio calculations for events on a much smaller scale than neural activity, so discussion of field is irrelevant. A quick browse of the literature settles this.
Arguments from formal epistemology invoking Goedel's Incompleteness Theorems à la Lucas-Penrose and the writings of Haim Gaifman are rooted in misunderstanding of the implications of results in mathematical logic for the theory of computation as well as the formal definition of undecidability. Comments from Hilary Putnam and more recently Avi Widgerson provide an accessible summary. 04:35, 27 September 2015 (UTC)
Be honest in the opening argument for quantum consciousness.
I changed the opening argument because it is a strawman of the actual reasons given for quantum consciousness. If you want to disagree with it fine, if you want to call it pseudoscience also fine, but at least be honest about the motivations given for it. - — Unsigned, by: 126.96.36.199 / talk / contribs 22:48, 3 November 2015
- Reasons which are God of the gaps, which is precisely what it said.
- 1) Something must explain X - (Something must explain thunder/Something must explain tides)
- 2) The only thing that seems to explain it is Y - (The only thing I can think of is Zeus bowling/The only thing I can think of is God)
- 3) Therefor Y causes X - (Therefor thunder is caused by Zeus bowling/Therefore God makes the tides)
- The only difference is changing a god to quantum and adding a few extra letters. Replace quantum with bunnies, god, or angel farts and the syllogism still makes as much sense. -EmeraldCityWanderer (talk) 23:19, 3 November 2015 (UTC)
Quantum Information & Consciousness
It is unfortunate that quantum woo is everything that comes to mind when the two words quantum and consciousness are mentioned in a single sentence. Below I post a reference to a monograph that might be useful to the readers of this article.
- Georgiev, Danko D. (2017). Quantum Information and Consciousness: A Gentle Introduction. Boca Raton: CRC Press. ASIN B077YQCZ7N. ISBN 9781138104488. OCLC 1003273264.
- I've not read the book so I know nothing about it, but there is certainly a tendency in skeptical circles to equate quantum+anything to woo. This is understandable as, historically, quantum+anything has indeed turned out to be woo. But each claim really needs to be investigated on its own merits.

- I think that the test proposed by Brian Cox to challenge woo meisters to first solve the Schrödinger equation (for a simple system) is a good way to separate non-sense from science. Currently, the article on quantum consciousness is fun to read on Rational Wiki (as opposed to quantum mind), but I think that what is said just repeats the article on quantum woo. For example, Deepak Chopra is definitely not a theorist, and some quantum physicists who have published multiple books on quantum mind are not even mentioned here. For example, Henry Stapp has published 3 books with Springer. Danko Georgiev (talk) 22:34, 27 December 2017 (UTC)
Joining the chorus here. Weird as it may be, there actually are quantum vibrations in the space between neurons just like Penrose and Hammeroff claimed. The idea of quantum mechanic being related to consciousness is something people have made RIDICULOUS claims about but there's nothing fundamentally wrong about it as a theory. === CT Phipps — Unsigned, by: 188.8.131.52 / talk / contribs
- What does "quantum vibration" even mean? I must say I am ware of those who keep using the word "quantum" without knowing what it means. Nerd (talk) 03:01, 21 January 2018 (UTC)
- Basically, the stuff which Hammeroff and Penrose speculated would be the source of consciousness and the actual stuff generating thoughts in the brain unlike neurons. In this case, we can observe the effect like electricity in the brain and the debate is Hameroff says it's where consciousness is happening and draws quite a few more conclusions from. — Unsigned, by: 184.108.40.206 / talk / contribs
Well the big difference between everyone else in the world and quantum consciousness and Roger Penrose is the fact he actually knows...well, more than about anyone else alive about quantum physics. https://en.wikipedia.org/wiki/Roger_Penrose — Unsigned, by: 220.127.116.11 / talk 15:07, 8 February 2018 (UTC)
- Roger Penrose may know quantum mechanics, but Stuart Hameroff is the one who wrote all the nonsense stuff on "Hameroff-Penrose Orch OR", "quantum vibrations in microtubules", "Platonic values embedded in fundamental space-time geometry", "consciousness diffusing in the universe at large in near-death-experiences", etc. Penrose's contribution is the calculation of gravitational self-energy in an old 1996 paper. Since then, Hameroff-Penrose papers contain no equations besides E = h/T, and quantum mumbo-jumbo speculations. Stuart Hameroff knows nothing about quantum mechanics and has collaborated a number of articles with Deepak Chopra. The Hameroff-Chopra collaboration is the finest of all examples of pseudoscience, and quantum mumbo-jumbo. Brian Cox's challenge for one to solve the Schrödinger equation for some very simple potential is a valid test to distinguish quantum charlatans from real scientists.

Do we need to put the word "theoretical" in parentheses after saying that the quantum computer is a real device? Why can't we just say now, as 2019 ends, that it is a real device full stop? And reality is the opposite of woo. https://www.nytimes.com/2019/10/23/technology/quantum-computing-google.html — Unsigned, by: Christofurio / talk / contribs
