The quantum mind hypothesis posits that consciousness cannot be fully explained by classical physics or neuronal interactions alone, suggesting instead that quantum phenomena like entanglement and superposition in the brain's microscopic structures may play a critical role. Early ideas explored by physicists such as Eugene Wigner linked consciousness to quantum mechanics, while David Bohm proposed an "implicate order" from which both mind and matter emerge. The most prominent theory, "orchestrated objective reduction" (Orch-OR) by Roger Penrose and Stuart Hameroff, suggests that consciousness arises from quantum computations within neuronal microtubules, partly inspired by Penrose's insights from Gödel's incompleteness theorems. However, these ambitious hypotheses remain unvalidated, facing significant skepticism from many scientists and philosophers, including Victor Stenger and David Chalmers, who characterize them as lacking scientific basis and failing to resolve the fundamental "hard problem" of consciousness.
