摘要
解决核多体问题的计算限制可以通过利用量子计算机来克服。核壳模型计算提供了对原子核性质的更深入见解，这是一种随参与粒子数量而指数增长的Hilbert空间大小的高资源需求案例。正在开发量子算法来克服这些挑战并推进此类计算。为了开发核壳模型的量子电路，利用噪声中间规模量子（NISQ）设备的能力。我们旨在最小化资源需求（特别是比特数和门数），并通过采用相关的纠缠技术来减少噪声的影响。我们通过设计基于Givens旋转的优化变分量子本征求解器（VQE） ansatz，并将qubit-ADAPT-VQE与变分量子分解（VQD）结合用于计算基态和激发态，同时包含零噪声外推技术，以实现对38Ar和6Li的基态和激发态能级的更高精度。这些能级分别以无噪声模拟、噪声条件和应用噪声缓解技术后的结果呈现。我们比较了Jordan-Wigner和Gray编码在VQE、qubit-ADAPT-VQE和VQD中的结果。我们的工作凸显了噪声鲁棒协议在扩大核壳模型计算中发挥的潜力。
