Entropy of a quantum channel

Year: 2021

Type: article

Abstract: The authors generalize the von Neumann entropy from quantum states to quantum channels, which model evolutions of quantum physical systems, and they provide a physical interpretation of a quantum channel's entropy in terms of an information-processing task called quantum channel merging.
