Abstract

Quantum annealing is a method for finding the global minimum of a given objective function by using quantum fluctuations and is used mainly for combinatorial optimization problems where the search space is discrete. For ideal quantum annealing quantum bits which have long coherence time and scalability are necessary, and superconducting circuits are promising candidates for them. This is because high coherence is expected due to superconducting phenomena and high integration is realized by solid-state devices. In this paper quantum annealing based on superconducting parametric oscillators and related technology are introduced.
