在这篇论文中，我们探讨了量子退火（QA）及其应用在开放系统设置中的行为。我们给出了量子退火器件时变开放动力学的有效并行模拟方法的推导和数值公式。我们考虑了环境的弱耦合极限以及1/f噪声的情况。随机时变量子轨迹技术可用于研究量子退火中的弱测量和反馈误差校正。然后重点讨论了反向退火（RA）的开放系统描述，这是量子退火的一个有前途的变体和应用。我们表明，使用各种模拟工具，反向退火可以受益于退火炉与其环境之间的相互作用。
In this dissertation, we explore how quantum annealing (QA) and its applications behave in an open system setting. We give derivations and numerical recipes for effective parallel simulation methods for time-dependent open dynamics of quantum annealing devices. We consider the weak-coupling limit to an environment and also the case of $1/f$ noise. The stochastic time-dependent quantum trajectories technique can be utilized in studying weak measurements and feedback error correction in quantum annealing. Then we focus on opensystem descriptions of reverse annealing (RA), which is a promising variant and application of quantum annealing. We show that, with various simulation tools, reverse annealing can benefit from the interaction between the annealer and its environment.
