关于嵌入的状态空间结构
The Structure of State Space with Respect to Imbedding
摘要:
形成的纠缠以及条件熵可以用来定义状态空间中的叶子,由它们的极值点的线性叠加给出。给出的例子中,这些叶子可以指定,并可用于计算纠缠分别的条件熵。纠缠的定义被推广到无限系统,并允许再次定义一个叶结构。最后,我们评论这两个表达式的可加性属性,提供一个反例的条件熵的可加性。
英文摘要:
The entanglement of formation as well as the conditional entropy can be used to define leaves in the state space, given by a linear superposition of their extremal points. Examples are presented, where these leaves can be specified and can be used to calculate the entanglement respectively the conditional entropy. The definition of entanglement is generalized to infinite systems and allows again to define a leaf structure. Finally we remark on the additivity property of both expressions, offering a counter example to the additivity of the conditional entropy.
