Part 3/9:
However, the primary challenge to Penrose's hypothesis is the environment in which the human brain operates. The brain is warm, noisy, and intricately dynamic, conditions that are generally unfavorable for maintaining quantum coherence—an essential requirement for any meaningful quantum computation. Contemporary quantum computers operate under extremely controlled environments, often cooled to near absolute zero to preserve quantum states long enough for calculations. If Penrose's theory is to hold water, quantum effects would need to be preserved within neurons until they fire, which current estimations deem unlikely.
