Quasi-Entropies and Non-Markovianity [PDF]
Entropy, 2019 We address an informational puzzle that appears with a non-Markovian open qubit dynamics: namely the fact that, while, according to the existing witnesses of information flows, a single qubit affected by that dissipative dynamics does not show ...

Thermodynamic power of non-Markovianity. [PDF]
Sci Rep, 2016 AbstractThe natural framework to discuss thermodynamics at the quantum level is the theory of open quantum systems. Memory effects arising from strong system-environment correlations may lead to information back-flow, that is non-Markovian behaviour. The relation between non-Markovianity and quantum thermodynamics has been until now largely unexplored.

Pure non-Markovian evolutions [PDF]
Quantum, 2023 Non-Markovian dynamics are characterized by information backflows, where the evolving open quantum system retrieves part of the information previously lost in the environment.

Squashed quantum non-Markovianity: a measure of genuine quantum non-Markovianity in states [PDF]
QuantumQuantum non-Markovianity in tripartite quantum states $\rho_{ABC}$ represents a correlation between systems $A$ and $C$ when conditioned on the system $B$ and is known to have both classical and quantum contributions.

Precursors of non-Markovianity
New Journal of Physics, 2019 Using the paradigm of information backflow to characterize a non-Markovian evolution, we introduce so-called precursors of non-Markovianity, i.e. necessary properties that the system and environment state must exhibit at earlier times in order for an ...

Quantification of memory effects in topological two-band open quantum systems [PDF]
HeliyonWe incorporate non-Markovian profiles and Linear Response Theory to analyze memory effects in two-band topological quantum systems. Furthermore, we have applied a measure of non-Markovianity in terms of nonlinear optical spectroscopy.

Eternal non-Markovianity: from random unitary to Markov chain realisations [PDF]
Scientific Reports, 2017 The theoretical description of quantum dynamics in an intriguing way does not necessarily imply the underlying dynamics is indeed intriguing. Here we show how a known very interesting master equation with an always negative decay rate [eternal non ...

Critical Assessment of Information Back-Flow in Measurement-Free Teleportation [PDF]
EntropyWe assess a scheme for measurement-free quantum teleportation from the perspective of the resources underpinning its performance. In particular, we focus on claims recently made about the crucial role played by the degree of non-Markovianity of the ...

Witness of non-Markovian dynamics based on Bhattacharyya quantum distance [PDF]
Scientific ReportsNon-Markovian effects due to quantum memory in the dynamics of open systems typically correspond to information backflows from the surrounding environment to the system.

Non-Markovian Quantum Jumps [PDF]
Physical Review Letters, 2008 Open quantum systems that interact with structured reservoirs exhibit non-Markovian dynamics. We present a quantum jump method for treating the dynamics of such systems. This approach is a generalization of the standard Monte Carlo Wave Function (MCWF) method for Markovian dynamics.
