Heat engines usually operate by exchanging heat with thermal baths at different (positive)
temperatures. Nonthermal baths may, however, lead to a significant performance boost …

We investigate the evolution of a target qubit caused by its multiple random collisions with N-
qubit clusters. Depending on the cluster state, the evolution of the target qubit may …

In this article, single, and two‐qubit central spin systems interacting with spin baths are
considered and their dynamical properties are discussed. The cases of interacting and non …

We establish a convex resource theory of non-Markovianity inducing information backflow
under the constraint of small time intervals within the temporal evolution. We identify the free …

There are certain dynamics which although are non-Markovian but never show information
backflow. We show that if two such dynamical maps are considered in a scenario where the …

The generation of steady quantumness in the presence of an environment is of utmost
importance if we are to build practical quantum devices. We propose a scheme of …

The focus is on understanding the quantum thermodynamics of strongly coupled non-
Markovian quantum systems. To this end, a non-trivial, non-Markovian model of a central …

Several recent studies have demonstrated the utility of the quantum switch as an important
resource for enhancing the performance of various information processing tasks. In a …

Non-Markovian effects in open quantum system dynamics usually manifest the backflow of
information from the environment to the system, indicating complete-positive divisibility …

We propose the notion of quantum coherence for superpositions over states which are not
necessarily mutually orthogonal. This anticipatedly leads to a resource theory of non …
