经典和量子退火的情况下，讨论了一个广义的动力学约束的模型，其中的松弛动力学系统与平凡的基态被推迟的能量障碍的外观在松弛路径，遵循当地的动力学规则。热和量子涨落在克服这些动力学障碍，达到基态的有效性进行了研究。已经表明，对于某些势垒特性，量子退火可能远远超过其热对应部分更快地达到基态。
Classical and quantum annealing is discussed in the case of a generalized kinetically constrained model, where the relaxation dynamics of a system with trivial ground state is retarded by the appearance of energy barriers in the relaxation path, following a local kinetic rule. Effectiveness of thermal and quantum fluctuations in overcoming these kinetic barriers to reach the ground state are studied. It has been shown that for certain barrier characteristics, quantum annealing might by far surpass its thermal counter part in reaching the ground state faster.
