Quasi-eternally non-Markovian channels with a multiply singular generator

26 Feb 2020 Shrikant U. Rao Vinod N. Srikanth R. Banerjee Subhashish

We propose and study in detail a class of qubit depolarizing channels that are asymmetrically non-Markovian and are characterized by up to three singularities in the generator. The three canonical decoherence rates are shown to flip sign after each singularity... (read more)
