Abstract:
1. A quantum computer that performs quantum calculation using quantum bits, comprising: a quantum bit substrate which includes a Mott insulator thin film at which one or more holes or one or more electrons are doped during manufacturing; a magnetic field generating unit which applies a magnetic field onto the quantum bit substrate in order to generate a spin vortex centered on each hole, or each electron, that is formed at the Mott insulator thin film and thereby create a quantum bit, by generating a clockwise or counterclockwise loop current corresponding to the generated spin vortex state, while also providing an energy difference to two generated spin vortex states thereof; a quantum calculation data supply unit which generates and irradiates an electromagnetic wave including quantum calculation data with a strength required for causing each hole, or each electron, to be able to perform a Rabi oscillation at the quantum bit substrate; and a quantum calculation result read-out unit, which extracts a quantum calculation result of the quantum bit substrate, by irradiating a strong coherent light pulse with a narrowed beam diameter onto the quantum bit substrate, in order to analyze a polarization of the resulting reflected light or transmitted light at the quantum bit substrate.
