摘要: 随着量子计算技术的快速发展,量子电路运行时间和额外门插入成本成为实现高效量子电路调度的主要挑战。为此,文中提出了多策略融合的小龙虾优化算法MPF-COA(Multi-strategy fusion-COA)。通过自定义优化初始种群并结合基于熵的自适应机制和信息素传递机制两个策略,实现了算法效率和精度的优化,并显著提升了复杂约束下量子电路调度的优化效率。初始种群的优化采用基于依赖关系的SWAP门插入策略DBSI(Dependency-Based SWAP Insertion Strategy),确保了更高质量的起始解。在此基础上,文中提出了基于熵的自适应温度调节机制,避免陷入局部最优解。信息素传递机制通过引导搜索方向,有效提高了全局最优解的搜索效率。实验验证采用2QAN量子计算框架,在包含4~22个量子比特规模的基准测试集上进行性能评估。结果表明,相较于2QAN,MPF-COA在t|ket〉中平均减少约3.2%的SWAP门数,CNOT门数量减少约4.69%,在Qiskit中平均减少约10.68%的SWAP门数,CNOT门数量减少约11.89%。文中展示了仿生算法与量子电路调度的深度融合潜力,为未来面向更大规模量子电路的调度与优化提供了可持续的研究基础。
