Sign Up to like & getrecommendations! Published in 2018 at "Physics Reports"
DOI: 10.1016/j.physrep.2018.07.001
Abstract: Markovian approximation is a widely-employed idea in descriptions of the dynamics of open quantum systems (OQSs). Although it is usually claimed to be a concept inspired by classical Markovianity, the term quantum Markovianity is used… read more here.

DOI: 10.1038/s41534-020-0283-3
Abstract: The dynamics of open quantum systems and manipulation of quantum resources are both of fundamental interest in quantum physics. Here, we investigate the relation between quantum Markovianity and coherence, providing an effective way for detecting… read more here.

DOI: 10.1088/1751-8121/abd191
Abstract: We establish a convex resource theory of non-Markovianity under the constraint of small time intervals within the temporal evolution. We construct the free operations, free states and a generalized bona-fide measure of non-Markovianity. The framework… read more here.

DOI: 10.1103/physreva.96.032125
Abstract: We investigate the effect of counter-rotating-wave terms on the non-Markovianity in quantum open systems by employing the hierarchical equations of motion in the framework of the non-Markovian quantum state diffusion approach. As illustrative examples, the… read more here.

DOI: 10.1103/physreva.96.062118
Abstract: Calculating the degree of non-Markovianity of a dissipative process is a difficult task, even for the dynamics of a single qubit, given the complex maximization problem. In this work, focusing on the entanglement-based quantifier of… read more here.

DOI: 10.1103/physreva.97.032130
Abstract: We present a general framework for the information backflow (IB) approach of Markovianity, that not only includes a large number, if not all, of IB prescriptions proposed so far, but also is equivalent to CP-divisibility… read more here.

DOI: 10.1103/physreva.98.043850
Abstract: The way a principle system and its environment interact characterizes the non-Markovianity of the dynamics. Herein, we investigate the non-Markovian dynamics of photon polarization in a birefringent crystal. We consider the so-called `quantity of quantum-mechanical… read more here.

DOI: 10.3390/e22080895
Abstract: Based on conditional past–future (CPF) correlations, we study the non-Markovianity of a central spin coupled to an isotropic Lipkin–Meshkov–Glick (LMG) bath. Although the dynamics of a system is always non-Markovian, it is found that some… read more here.

DOI: 10.3390/e25050756
Abstract: We studied the tunable control of the non-Markovianity of a bosonic mode due to its coupling to a set of auxiliary qubits, both embedded in a thermal reservoir. Specifically, we considered a single cavity mode… read more here.
