Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

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 …

Within the unified framework of exploiting the relative entropy as a distance measure of
quantum correlations, we make explicit the hierarchical structure of quantum coherence …

We analyze under which dynamical conditions the coherence of an open quantum system is
totally unaffected by noise. For a single qubit, specific measures of coherence are found to …

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

We report an experimental investigation of quantum correlations in a two-qutrit spin system
in a single nitrogen-vacancy center in diamond at room temperatures. Quantum …

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 …

Quantum entanglement of identical particles is essential in quantum information theory. Yet,
its correct determination remains an open issue hindering the general understanding and …

In many applications entanglement must be distributed through noisy communication
channels that unavoidably degrade it. Entanglement cannot be generated by local …
