摘要： According to the present invention, there is provided a correlation tunnel device capable of achieving a low power consumption without decreasing a drive force when a large-scale-integrated circuit is constituted. A correlation tunnel device according to the present invention comprises a first quantum dot structure including a first carrier confinement region having at least two discrete energy levels, a carrier conduction region adjacent to the first carrier confinement region, and a tunnel barrier arranged only between the first carrier confinement region and the conduction region, and a second quantum dot structure including a second carrier confinement region having at least two discrete energy levels, a carrier conduction region adjacent to the second carrier confinement region, and a tunnel barrier arranged only between the second carrier confinement region and the conduction region, wherein an energy level occupied by the carrier in the first carrier confinement region and an energy level occupied by the carrier in the second carrier confinement region have a correlation.

摘要： A quantum computer comprises a crystal lattice having storage atoms. The storage atoms have nuclear storage spins, and quantum bits are stored as orientations of the storage spins. A magnetic field is applied to the crystal, the magnetic field having a gradient on the order of 1T/&mgr;m. The gradient is generated by a micromagnet. The electrons of the crystal acquire a regular order, and the storage spins are initialized by inducing combined electron-nucleus transitions in the crystal, thereby transferring the electronic order to the storage spins. The storage spins are decoupled from each other by a decoupling magnetic field. Quantum logic operations are performed on the storage spins. Certain quantum logic operations require a modification of the decoupling field to recouple a plurality of the storage spins. Final polarizations of the storage spins are measured.
