Title:
QUANTUM ANNEALING COMPUTING DEVICE, QUANTUM ANNEALING COMPUTING METHOD, AND QUANTUM ANNEALING COMPUTING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/245877
Kind Code:
A1
Abstract:
A quantum annealing computing device 20 compriese a computing unit 21 for computing logcoth (βαr/m) (β denotes a fixed parameter, m denotes a Trotter number, α denotes a value 0 or greater to less than 1, r denotes the number of arithmetic operationswhich is the coefficient of a term that represents a transverse magnetic field in the Hamiltonian of a transverse magnetic field Ising model by approximation to logcoth (βαr/m) ≒ log(2)−log(2 β/m)−rlog( α) when αr ≒ ０.
