Is There Evidence Supporting Brains as Quantum Computers?

Click For Summary
SUMMARY

The discussion centers on the claim that human brains may function as quantum computers, a theory popularized by theoretical physicist Roger Penrose. However, this notion lacks acceptance among mainstream neuroscientists, who widely criticize quantum mind theories. Currently, there is insufficient evidence to support the idea that brains operate on quantum principles, making it an inappropriate topic for further exploration in this forum. Consequently, those interested in quantum computation should approach the subject with caution, particularly regarding its relevance to machine learning.

PREREQUISITES
  • Understanding of quantum mechanics fundamentals
  • Familiarity with quantum computation concepts
  • Basic knowledge of machine learning principles
  • Awareness of neuroscience and its critiques of quantum theories
NEXT STEPS
  • Research quantum mechanics basics to grasp underlying principles
  • Explore quantum computing applications in machine learning
  • Investigate critiques of quantum mind theories by neuroscientists
  • Study the implications of Penrose's theories on consciousness and computation
USEFUL FOR

Individuals interested in the intersection of neuroscience and quantum computing, particularly machine learning researchers and students exploring theoretical frameworks in cognitive science.

I've heard it claimed before that brains could be quantum computers (I think it was on Through the Wormhole). Is there any evidence of this?

I'm thinking about reading up on quantum computation, but don't know anything about quantum mechanics yet. I'm mostly interested in machine learning, and not yet sure if quantum computing is a worthwhile thing to study. I.e. I'm not sure if quantum computers are possible/practical. If brains are quantum computers, then I would at least know quantum computing is possible and practical in some sense.

No; the theory was made popular by a theoretical physicist (Penrose). It's not accepted by mainstream neuroscientists.
 
Quantum mind theories have been widely criticised and if they ever meet a burden of proof they can be discussed. Right now though they are not appropriate for this forum.
