Markov states have been defined for tripartite quantum systems. In this paper, we generalize the definition of the Markov states to arbitrary multipartite case and find the general structure of an important subset of them, which we will call strong Markov states. In addition, we focus on an important property of the Markov states: If the initial state of the whole system–environment is a Markov state, then each localized dynamics of the whole system–environment reduces to a localized…

Positivity of the assignment map implies complete positivity of the reduced dynamics
If there exists a positive assignment map, then the so-called reference state is a Markov state, which implies that there exists another assignment map which is completely positive, which means the reduced dynamics of the system is also completely positive.


Entanglement increase from local interaction in the absence of initial quantum correlation in the environment and between the system and the environment
We consider a bipartite quantum system S=AB such that the part A is isolated from the environment E and only the part B interacts with E. Under such circumstances, entanglement of the system may
Revival of quantum correlations without system-environment back-action
Revivals of quantum correlations have often been explained in terms of back-action on quantum systems by their quantum environment(s). Here we consider a system of two independently evolving qubits,
Distributed correlations and information flows within a hybrid multipartite quantum-classical system
Understanding the non-Markovian mechanisms underlying the revivals of quantum entanglement in the presence of classical environments is central in the theory of quantum information. Tentative
Operations that do not disturb partially known quantum states
Consider a situation in which a quantum system is secretly prepared in a state chosen from the known set of states. We present a principle that gives a definite distinction between the operations
Entanglement dynamics of two independent qubits in environments with and without memory
Here is analyzed the dynamics of two-qubit entanglement, when the two qubits are initially in a mixed extended Werner-like state and each of them is in a zero temperature non-Markovian environment.
Overview on the phenomenon of two-qubit entanglement revivals in classical environments
The occurrence of revivals of quantum entanglement between separated open quantum systems has been shown not only for dissipative non-Markovian quantum environments but also for classical
Non-markovian effects on the dynamics of entanglement.
It is shown that, although no interaction is present or mediated between the qubits, there is a revival of their entanglement, after a finite period of time of its complete disappearance.
Experimental on-demand recovery of entanglement by local operations within non-Markovian dynamics
This work demonstrates in two all-optical experiments that entanglement restoration can even be achieved on-demand in the presence of non-Markovian dynamics, and implements an open-loop control scheme based on a purely local operation and a closed-loop scheme that relies on local control.
Recovering entanglement by local operations
We investigate the phenomenon of bipartite entanglement revivals under purely local operations in systems subject to local and independent classical noise sources. We explain this apparent paradox in
Experimental recovery of quantum correlations in absence of system-environment back-action
A simple two-qubit model is introduced and an all-optical experiment is reported which simulates the model and permits us to recover and control, against decoherence, quantum correlations without back-action.
