Characterization of a damping channel as a mixture of amplitude damping and anti-damping channels of different parameters
Vijay Pathak, R. Srikanth
Non-unital noise is a fundamental feature of open quantum systems, governing energy exchange and inducing state translations on the Bloch sphere. While such translations can be use…

On the distinction between distinguishability of states and witness of non-Markovianity of dynamical maps
Vijay Pathak, R. Srikanth
Non-P-divisibility is the strongest divisibility-based notion of quantum non-Markovianity. The generalized trace distance (GTD) based criterion is known to be an optimal witness of…
