Information flow versus divisibility for qubit evolution

11 Jan 2019 Chakraborty Sagnik Chruściński Dariusz

We study the relation between lack of Information Backflow and completely positive divisibility (CP divisibility) for non-invertible qubit dynamical maps. Recently, these two concepts were shown to be fully equivalent for the so called image non-increasing dynamical maps... (read more)
