"quantum information systems' high accuracy/ low error involves difficult to scale trapped dilute gaseous atomic ions, tried using solid material, but then very sensitive to interference, overcome using scalable monolayer-protected gold clusters... electron spin direction/ its alignment with respect to other electrons in system directly impact quantum information systems' accuracy/ longevity, including spin-polarized states mimicing super-positions... high spin polarization maintain correlation/ accuracy for much longer time"
