主 题: Structure of reversible quantum channels
报告人：李愿
摘 要：Reversibility of quantum channels is a fundamental and key issue in quantum dynamics, with unitary evolutions as prototypical examples. In this work, we provide some characterizations of reversible quantum channels by relating recovery maps of reversible quantum channels with their dual maps. We further analyze the structure of recovery maps of reversible quantum channels and provide a decomposition result for them. These structural results reveal some intrinsic aspects of reversible quantum channels and their recovery maps,.
