论文摘要
我们提出了一种实现多体量子状态分布的方法，灵感来自热力学和介观物理学的组合原理。它的本质是以保护法为条件的最大熵原则。我们超越了传统的热力学和条件，在保守量的全部分布方面。结果是量子状态分布，其偏离“热状态”的偏差在广泛输入分布的极限下变得更加明显。我们在纠缠措施方面描述了它们的特性，并通过当前日期实验的方法讨论了国家工程的策略。
We propose an approach to the realization of many-body quantum state distributions inspired by combined principles of thermodynamics and mesoscopic physics. Its essence is a maximum entropy principle conditioned by conservation laws. We go beyond traditional thermodynamics and condition on the full distribution of the conserved quantities. The result are quantum state distributions whose deviations from `thermal states' get more pronounced in the limit of wide input distributions. We describe their properties in terms of entanglement measures and discuss strategies for state engineering by methods of current date experimentation.
