Temporal self-similarity of quantum dynamical maps as a concept of memorylessness
Shrikant Utagi, R. Srikanth, Subhashish Banerjee
The problem of defining quantum non-Markovianity has proven elusive, with various in-equivalent criteria put forth to address it. The concept of CP-indivisibility and the hierarchy…

Non-Markovian dephasing and depolarizing channels
U. Shrikant, R. Srikanth, Subhashish Banerjee
We introduce a method to construct non-Markovian variants of completely positive (CP) dynamical maps, particularly, qubit Pauli channels. We identify non-Markovianity with the brea…
