If it can handle 500 qubits then according to the MWI that is 2^500 universes being involved in the calculation. Penrose would probably say that the superposition of 500 qubits would collapse the wavefunction (something to do with the difference between superposed worlds exceeding some gravitational threshold, I believe). So that's a falsification test which may become technologically feasible at some point. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
