论文摘要
我们绘制了所谓的J-方程式在量子信息理论中，涉及von Neumann熵的基本特性。最近提出了J-方程式作为Jarzynski方程的各种版本的祖先。它是在此处稍微推广的顺序测量的一般框架中得出的。
We sketch applications of the so-called J-equation to quantum information theory concerning fundamental properties of the von Neumann entropy. The J-equation has recently be proposed as a sort of progenitor of the various versions of the Jarzynski equation. It has been derived within a general framework of sequential measurements that is slightly generalised here.
