Abstract: This calculation model is a calculation model that is applicable to an Ising model or a QUBO, and includes a plurality of Ising bits and a first auxiliary bit, in which each of the plurality of Ising bits and the first auxiliary bit is a binary variable, and the plurality of Ising bits represents each of the options in combinatorial optimization problems as a combination of the variables, and the first auxiliary bit indicates a value obtained by performing logical calculation on two or more values among a plurality of values indicating the options.

Abstract: A spin inductor has a first inductor layer, a first terminal, and a second terminal. The first inductor layer includes a first wiring layer and a first ferromagnetic layer in contact with the first wiring layer. The first terminal is in contact with a first lateral surface of the first inductor layer. The second terminal is in contact with a second lateral surface that is different from the first lateral surface of the first inductor layer. A virtual plane that connects a top edge and a bottom edge of the first lateral surface is inclined in the laminating direction.
