Ka taea te whakamahi i te rorohiko whatu ki te pūnaha arorau whatu. Ka taea e te rorohiko whatu e whakamahi ana i te muka whatu te whakamahi i te pouri rite 0 me nga polarizations orthogonal e rua o te marama rite 1 me −1. IBM hoki pūrongo auau i runga i ngā kaupapa rorohiko whatu (i roto i ona pepa), engari e kore te reira i te hohe i roto i te reira. Kua tūtohutia te junction Josephson rite te pūtau mahara whaitake, te whakamahi i rere superconducting nāianei, rānei te ara karaka, te ara karaka, ranei. "Ko nga painga o te tere rorohiko taketake o te rorohiko whaitake ko te kaha rorohiko taketake, me te kore noa iho i te maha o ngā huānga qubit".
