求解QUBO问题的量子退火学习搜索

Quantum Annealing Learning Search for solving QUBO problems

Enrico Blanzieri, Davide Pastorello

摘要:

在本文中,我们提出了一种新的策略来解决优化问题的混合量子经典计划的基础上量子退火,特别关注QUBO问题。所提出的算法是基于一个迭代的结构,其中的目标函数的表示到退火架构的学习和已经访问的解决方案是由禁忌启发搜索惩罚。其结果是一个启发式搜索配备了学习机制,以提高编码的问题到量子架构。我们证明了算法的收敛到一个全局最优的情况下,一般的QUBO问题。我们的技术是一种替代的直接减少到稀疏退火图的给定的优化问题。

英文摘要:

In this paper we present a novel strategy to solve optimization problems within a hybrid quantum-classical scheme based on quantum annealing, with a particular focus on QUBO problems. The proposed algorithm is based on an iterative structure where the representation of an objective function into the annealer architecture is learned and already visited solutions are penalized by a tabu-inspired search. The result is a heuristic search equipped with a learning mechanism to improve the encoding of the problem into the quantum architecture. We prove the convergence of the algorithm to a global optimum in the case of general QUBO problems. Our technique is an alternative to the direct reduction of a given optimization problem into the sparse annealer graph.
