量子不和谐与麦克斯韦的恶魔

Quantum Discord and Maxwell's Demons

Wojciech Hubert Zurek

摘要:

量子不和谐被提出作为相关性的“量子性”的信息论度量。我表明,不和谐决定了量子和经典麦克斯韦恶魔的效率之间的差异-也就是说,实体,可以或不能测量非局部观测或进行条件量子操作-在提取相关的量子系统的集合工作。

英文摘要:

Quantum discord was proposed as an information theoretic measure of the ``quantumness'' of correlations. I show that discord determines the difference between the efficiency of quantum and classical Maxwell's demons -- that is, entities that can or cannot measure nonlocal observables or carry out conditional quantum operations -- in extracting work from collections of correlated quantum systems.
