Sequential measurements and entropy
arXiv:2001.04400 · doi:10.1088/1742-6596/1638/1/012007
Abstract
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.
