Microtubules as a Quantum Hopfield Network

摘要: Penrose and Hameroff’s orchestrated objective (Orch OR) theory CHEXX[14] suggests the existence of quantum computation in microtubule protein assemblies inside living cells. To investigate this suggestion numerically, we model system as a Hopfield network (QHN) with qubits representing tubulins interacting coulombically each other, at finite temperatures. The effects energy losses, dissipation, other environmental factors are not considered, or considered to be screened. Simulations carried out on computational model, look for stable states (local minima) network. We find that information processing microtubules is feasible, though temperatures (5.8 K) lower than physiological
