  • Patent number: 11341425
    Abstract: A computing apparatus that does not need quantum coherence or a cryogenic cooling apparatus is provided for assignments that need an exhaustive search. A system is led to the ground state of the system where a problem is set, wherein spin sjz that is a variable follows a local effective magnetic field Bjz. The spin state at t=0 is initialized with a transverse field (in the x-direction). This corresponds to sjz=0. With time t, the magnetic field in the z-axis direction and the inter-spin interactions are gradually added, and finally the spin is directed to the +z- or ?z-direction. The z component of the spin sj is sjz=+1 or ?1. Here, in the process where the orientation of the spin sjz follows that of the effective magnetic field Bjz, correction parameters originating in quantum-mechanical effects are introduced and ground-state-maintaining performance is improved.
