摘要:

我们研究了一类用于Lindblad方程的保结构确定性数值格式。这类格式形式简洁,理论上可系统地达到任意高阶精度。此外,这些格式还能克服许多传统数值格式产生的非物理问题。由于保留了物理性质,这些格式可直接作为骨干框架,用于进一步开发模拟Lindblad方程的随机算法和量子算法。在本工作中,我们系统研究了这类保结构确定性格式,开展了详细的误差分析,并通过数值算例验证了分析结果。

英文摘要:

We study a family of structure-preserving deterministic numerical schemes for Lindblad equations. This family of schemes has a simple form and can systemically achieve arbitrary high-order accuracy in theory. Moreover, these schemes can also overcome the non-physical issues that arise from many traditional numerical schemes. Due to their preservation of physical nature, these schemes can be straightforwardly used as backbones for further developing randomized and quantum algorithms in simulating Lindblad equations. In this work, we systematically study this family of structure-preserving deterministic schemes and perform a detailed error analysis, which is validated through numerical examples.
