Quantum particles cannot copy themselves. That's not a quirk but a mathematical prohibition. It prevents a purely quantum system from thinking and making decisions — the mind definitely needs a piece of the classical world. Perhaps our brain is a mixture of both.
🎯 The no-cloning theorem states: it is impossible to create an exact copy of an arbitrary unknown quantum state. This is not a technical limitation but a fundamental law of nature.
🎬 In science fiction, the idea of quantum consciousness appears frequently (for instance, in Hannu Rajaniemi's novel 'The Quantum Thief'), but new results show that without a classical component, no quantum 'thinking' is possible.
