We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

We calculate the dissipative dynamics of two-qubit quantum discord under Markovian
environments. We analyze various dissipative channels such as dephasing, depolarizing …

Recently some authors have pointed out that there exist nonclassical correlations which are
more general, and possibly more fundamental, than entanglement. For these general …

We evaluate the quantum discord dynamics of two qubits in independent and common non-
Markovian environments. We compare the dynamics of entanglement with that of quantum …

In the current era of noisy intermediate-scale quantum (NISQ) devices, research on the
theory of open system dynamics has a crucial role to play. In particular, understanding and …
