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 …

Quantum technology relies on the utilization of resources, like quantum coherence and
entanglement, which allow quantum information and computation processing. This …

We examine the system-reservoir dynamics of classical and quantum correlations in the
decoherence phenomenon within a two-qubit composite system interacting with two …

Quantum Fisher information of a parameter characterizes the sensitivity of the state with
respect to changes of the parameter. In this article, we study the quantum Fisher information …

Entanglement of a system changes due to interactions with the environment. A typical type of
interaction is amplitude damping. If we add a detector to monitor the environment and only …
