论文摘要
开放量子系统为开发新型量子技术提供了基本的理论基础，因为任何实际量子系统都不可避免地与环境相互作用。 Lindblad Master方程捕获了Markovian环境的效果。封闭的量子系统可以使用粒子保护发电机的流动方程处理。我们将该发电机推广到由Lindbladians管辖的非静态矩阵和开放量子系统，将我们的结果与Rosso等人最近提出的发电机进行了比较。 （Arxiv：2007.12044）。相比之下，我们发现尽管截断，我们的主张发电机以良好的准确性提供了有效的流动。
Open quantum systems provide an essential theoretical basis for the development of novel quantum technologies, since any real quantum system inevitably interacts with its environment. Lindblad master equations capture the effect of Markovian environments. Closed quantum systems can be treated using flow equations with the particle conserving generator. We generalize this generator to non-Hermitian matrices and open quantum systems governed by Lindbladians, comparing our results with recently proposed generators by Rosso et al. (arXiv:2007.12044). In comparison, we find that our advocated generator provides an efficient flow with good accuracy in spite of truncations.
