摘要翻译:
描述量子动力学的复杂性问题,特别是量子粒子的局部相互作用链的复杂性问题,将从几个不同的角度进行回顾和讨论:(i)运动对抗外部微扰和退相干的稳定性,(ii)从算符空间中的经典计算和纠缠产生的量子模拟效率,(iii)量子输运、弛豫到平衡和量子混合,(iv)量子动力学熵的计算。对所有这些准则的讨论将与已建立的可积性准则或量子混沌准则面临,有时会发现相当令人惊讶的结论。提出了量子多问题遍历理论中的一些猜想和有趣的开放问题。

英文摘要:
The problem of characterizing complexity of quantum dynamics - in particular of locally interacting chains of quantum particles - will be reviewed and discussed from several different perspectives: (i) stability of motion against external perturbations and decoherence, (ii) efficiency of quantum simulation in terms of classical computation and entanglement production in operator spaces, (iii) quantum transport, relaxation to equilibrium and quantum mixing, and (iv) computation of quantum dynamical entropies. Discussions of all these criteria will be confronted with the established criteria of integrability or quantum chaos, and sometimes quite surprising conclusions are found. Some conjectures and interesting open problems in ergodic theory of the quantum many problem are suggested.
