Hierarchy of quantum correlations under non-Markovian dynamics

نویسندگان

چکیده

We investigate the dynamics of quantum correlations (QC) under effects reservoir memory, as a resource for information and computation tasks. Quantum two-qubit systems are used implementing teleportation successfully, investigating how fidelity, violation Bell-CHSH inequality, steering entanglement connected with each other influence noisy environments. Both Markovian non-Markovian channels considered, it is shown that decay revival follow hierarchy in state space. Noise tolerance checked different types unital non-unital channels, without memory. The speed limit time $(\tau_{QSL})$ investigated from perspective memory noise, corresponding to analyze evolution correlations. establish connection between backflow, channels.

Non-markovian Dynamics of Open Quantum Systems

Title of dissertation: NON-MARKOVIAN DYNAMICS OF OPEN QUANTUM SYSTEMS Chris H. Fleming, Doctor of Philosophy, 2011 Dissertation directed by: Professor Bei-Lok Hu Department of Physics An open quantum system is a quantum system that interacts with some environment whose degrees of freedom have been coarse grained away. This model describes non-equilibrium processes more general than scattering-m...

Quantum dynamics with non-Markovian fluctuating parameters.

A stochastic approach to the quantum dynamics randomly modulated in time by a discrete state non-Markovian noise, which possesses an arbitrary nonexponential distribution of the residence times, is developed. The formally exact expression for the Laplace-transformed quantum propagator averaged over the stationary realizations of such N -state non-Markovian noise is obtained. The theory possesse...

Non-Markovian quantum dynamics from environmental relaxation

We consider the dynamics of composite quantum systems in the particular case that the state operator relaxes towards the Born approximation. For this we augment the von Neumann equation by a relaxation operator imposing a finite relaxation time τr . Under the premise that the relaxation is the dominant process we obtain a hierarchy of non-Markovian master equations. The latter arises from an ex...

Quantum Monte-Carlo for Non-Markovian dynamics

In fusion and fission processes, the reorganization of nucleons is fast with respect to the evolution of their relative distance and leads to dissipation in the motion of the nucleus. Thus, the internal degrees of freedom of the nucleus act as an environment which couples to the dynamics of the nucleus. One of the challenges in such an Open Quantum System is to incorporate non-Markovian effects...

Quantum speed limit for non-Markovian dynamics.

We derive a Margolus-Levitin-type bound on the minimal evolution time of an arbitrarily driven open quantum system. We express this quantum speed limit time in terms of the operator norm of the nonunitary generator of the dynamics. We apply these results to the damped Jaynes-Cummings model and demonstrate that the corresponding bound is tight. We further show that non-Markovian effects can spee...
