MAGNON MEDIATION TYPE SOLID NMR QUANTUM COMPUTER

摘要

PPROBLEM TO BE SOLVED: To provide a multiple-cubit type quantum computer that can select a cubit, can perform an arbitrary rotary gate operation, can switch a control NOT gate, and does not require any complex decoupling operation in a quantum computer using a solid nuclear magnetic resonance system using a magnetic field gradient. PSOLUTION: The quantum computer using the solid nuclear magnetic resonance system using the magnetic field gradient has a cubit where a nuclear spin I is set to every point of a plurality of lattice points in a low-dimensional magnetic body 1, selects the NMR frequency of electromagnetic waves 7 for performing the arbitrary rotary gate operation to a desired cubit, selects the frequency of microwaves 4 for generating magnon 5 between desired cubits, and then selects the NMR frequency of the electromagnetic waves 7 for performing the control NOT gate operation between desired cubits.
