  • Nuclear spin control device
    Patent number: 6614046
    Abstract: A nuclear spin control device comprises a first semiconducting layer with spin-up carriers, a second semiconducting layer with spin-down carriers; and a third semiconducting layer arranged between the first and the second semiconducting layers. The third semiconducting layer can be tunnelled selectively by the spin-up carriers and the spin-down carriers such that nuclear spin in the third semiconducting layer selectively interacts with the carriers so as to be oriented into a desired direction. The device may be adapted to control the shape of a wave function so as to cover nuclear spins in the third semiconducting layer and propagate information of one nuclear spin to another nuclear spin.
