For decades, the idea has been dismissed as too strange to take seriously. But experiments involving microtubules, anaesthetics and brain organoids are beginning to test whether quantum effects could play a role in consciousness.
We explore Roger Penrose and Stuart Hameroff鈥檚 controversial Orch OR theory, the evidence for and against it and whether quantum computers could one day help reveal what consciousness really is. We also venture into whether observation and consciousness could play a fundamental role in shaping reality itself.
