论文摘要
为了获得一些可行的产品设计,产品开发过程经常使用数值模拟和数学编程技术。尤其是拓扑优化是生成有见地的设计选择的最有希望的技术之一。拓扑优化问题减少了NP-HARD组合优化问题,其中优化了某些位置的材料的存在或不存在。在这项研究中,我们将量子计算机的用法作为拓扑优化问题的潜在解决方案。所提出的方法由两种变分量子算法(VQA)组成:第一个解决所有可能的材料构型的状态平衡方程,而第二个则使用第一个VQA的量子状态,第二个放大了量子叠加中最佳构型的可能性。包括真实设备实验在内的几个实验表明,所提出的方法成功地获得了最佳配置。这些发现表明,量子计算机可能是解决拓扑优化问题的潜在工具,它们打开了近距离产品设计的窗口。
To arrive at some viable product design, product development processes frequently use numerical simulations and mathematical programming techniques. Topology optimization, in particular, is one of the most promising techniques for generating insightful design choices. Topology optimization problems reduce to an NP-hard combinatorial optimization problem, where the combination of the existence or absence of the material at some positions is optimized. In this study, we examine the usage of quantum computers as a potential solution to topology optimization problems. The proposed method consists of two variational quantum algorithms (VQAs): the first solves the state equilibrium equation for all conceivable material configurations, while the second amplifies the likelihood of an optimal configuration in quantum superposition using the first VQA's quantum state. Several experiments, including a real device experiment, show that the proposed method successfully obtained the optimal configurations. These findings suggest that quantum computers could be a potential tool for solving topology optimization problems and they open the window to the near-future product designs.
