摘要翻译：
本文首先简要介绍了量子相变，强调了量子相变与经典热相变的异同。在指出量子相变带来的计算挑战之后，讨论了一些成功的计算方法。重点讨论了经典蒙特卡罗方法和量子蒙特卡罗方法，前者基于量子到经典的映射，而后者直接针对量子问题。这些方法通过清洁和无序体系中的几个量子相变实例加以说明。

英文摘要：
This article first gives a concise introduction to quantum phase transitions, emphasizing similarities with and differences to classical thermal transitions. After pointing out the computational challenges posed by quantum phase transitions, a number of successful computational approaches is discussed. The focus is on classical and quantum Monte Carlo methods, with the former being based on the quantum-to classical mapping while the latter directly attack the quantum problem. These methods are illustrated by several examples of quantum phase transitions in clean and disordered systems.
