Do quantum effects play a role in consciousness? – Physics WorldIn quantum biology, the quantum effects of superposition, coherence and decoherence, tunnelling, and entanglement play an important role. He theorized that light, which was conventionally accepted to behave as a continuous wave, might also be considered to propagate in discrete packages, or quanta, which we call photons. The researchers were looking to see whether neurotransmitter isotopes had differing effects, thus disqualifying the lock-and-key mechanism, which depends on shape, and supporting the possibility of vibration assisted tunnelling. Quantum tunnelling, meanwhile, involves a particle passing through an energy barrier despite lacking the energy required to overcome the barrier, as would be defined by classical physics. Finally, quantum entanglement allows two particles, such as photons or electrons, to have a much closer relationship than is predicted by classical physics. Over the years, it has played a central role in quantum technologies such as quantum cryptography, quantum teleportation and networks for distributing quantum information. It features in art, religion, literature and even in how we talk about knowledge – we speak of “enlightenment” and “seeing the light”, for example.
