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 …

Open quantum systems is the study of quantum dynamics of the system of interest, taking
into account the effects of the ambient environment. It is ubiquitous in the sense that any …

The problem of defining quantum non-Markovianity has proven elusive, with various in-
equivalent criteria put forth to address it. The concept of CP-indivisibility and the hierarchy of …

Recently, there has been an upsurge of interest in quantum thermodynamic devices, notably
quantum batteries. Quantum batteries serve as energy storage devices governed by the …

A master equation has been constructed for a global system–bath interaction in the both
absence and presence of non-Markovian noise. For the memoryless case, it has been …

We introduce a method to construct non-Markovian variants of completely positive (CP)
dynamical maps, particularly, qubit Pauli channels. We identify non-Markovianity with the …

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 consider two non-Markovian models: random telegraph noise and non-Markovian
dephasing. The memory in these models is studied from the perspective of quantum Fisher …

The non-Markovian depolarizing channel is explored from the perspective of understanding
its non-Markovian behavior as well as the occurrence of singularities. The study brings …

The ping-pong protocol adapted for quantum key distribution is studied in the trusted
quantum noise scenario, wherein the legitimate parties can add noise locally. For a well …
