Another bonus: once a magnetic field pushes an electron into a direction of spin, it will keep spinning the same way until another magnetic field causes the spin to change. This effect can be used to very quickly access magnetically stored information during computer operation -- even if the electrical power to a computer is switched off between uses. Data can be stored permanently, and is nearly instantly available anytime, no lengthy “boot up” needed. However, some practical problems still need to be solved: Spin state transfer through different materials.
