Singularities, mixing and non-Markovianity of Pauli dynamical maps
Shrikant Utagi, Vinod N. Rao, R. Srikanth +1
Quantum non-Markovianity of channels can be produced by mixing Markovian channels, as observed recently by various authors. We consider an analogous question of whether singulariti…

Quantum causal correlations and non-Markovianity of quantum evolution
Shrikant Utagi
A non-Markovianity measure for quantum channels is introduced based on causality measure - a monotone of causal (temporal) correlations - arising out of the pseudo-density matrix (…

Ping-pong quantum key distribution with trusted noise: non-Markovian advantage
Shrikant Utagi, R. Srikanth, Subhashish Banerjee
The ping-pong protocol adapted for quantum key distribution is studied in the trusted quantum noise scenario, wherein the legitimate parties can add noise locally. For a well-studi…
