We present a comprehensive and up-to-date review of the concept of quantum non-
Markovianity, a central theme in the theory of open quantum systems. We introduce the …

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 …

Quantum systems are invariably open, evolving under surrounding influences rather than in
isolation. Standard open quantum system methods eliminate all information on the …

Revivals of quantum correlations in composite open quantum systems are a useful
dynamical feature against detrimental effects of the environment. Their occurrence is …

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

All physical systems are to some extent open and interacting with their environment. This
insight, basic as it may seem, gives rise to the necessity of protecting quantum systems from …

Memory (non-Markovian) effect is found to be able to accelerate quantum evolution [S.
Deffner and E. Lutz, Phys. Rev. Lett. 111, 010402 (2013). PRLTAO 0031-9007 …

The degree of non-Markovianity of quantum processes has been characterized in several
different ways in the recent literature. However, the relationship between the non-Markovian …

We show that the phenomenon of frozen discord, exhibited by specific classes of two-qubit
states under local nondissipative decoherent evolutions, is a common feature of all known …
