AbstractWe introduce an quantum entropy for bimodule quantum channels on finite von Neumann algebras, generalizing the remarkable Pimsner-Popa entropy. The relative entropy for Fourier multipliers of bimodule quantum channels establishes an upper bound of the quantum entropy. Additionally, we present the Araki relative entropy for bimodule quantum channels, revealing its equivalence to the rela...
Abstract: One of the most fundamental questions in quantum information concerns with the amount of information that can be transmitted reliably through a quantum channel. For that, many capacities and entropies were introduced for describing the capability of the quantum channel for delivering information from the sender to the receiver. In this talk, we will explain how to obtain the exact val...
