The paper explores whether quantum effects in the brain could support the Copenhagen Interpretation, where wave function collapse occurs in the observer's mind. It simulates delayed luminescence of photons in neurons using a Brassard-like teleportation circuit, modeling the transfer of quantum states from retina to visual cortex. The simulation incorporates both classical and quantum processing in neurons. Results suggest it is possible for the brain to receive exact quantum states of photons in the visual cortex, which could then be collapsed by consciousness, supporting the Copenhagen Interpretation of the measurement problem.
The possibility of wave function collapse in the human brain has been debated since early quantum theory. Some scientists initially argued that collapse occurs in the brain or is caused by the observer's mind. Penrose and Hameroff proposed that quantum information processing in microtubules underlies consciousness via collective wave function collapse, while Tegmark argued thermal decoherence prevents any quantum processing in neurons. Rosa and Faber suggested a middle ground: despite decoherence, the brain could still be a quantum system. Thaheld concluded that quantum states of photons collapse in the eye, not the brain. This paper argues that together these views can describe different parts of a teleportation mechanism.
