Unidirectional Information Flow and Positive Divisibility are Nonequivalent Notions of Quantum Markovianity for Noninvertible Dynamics

چکیده
We construct a dynamical map which is not positive divisible and does present information backflow either (as measured by trace norm quantifiers). It formulated for qutrit system undergoing noninvertible dynamics. This provides an evidence that the two definitions of quantum Markovianity based on absence divisibility are nonequivalent general maps.

Non-Markovianity and the flow of information
To understand the information flow between a system and it environment, we based our studies on the decoherence program [1]where a system S is coupled to a measurement apparatus A, which in turn interacts with an environment E . In this sense, it introduces the concept of assisted knowledge, where the environment E , acquires information about a system S, by means of its measurement apparatus A.
متن کاملQuantum Zeno effect: Quantum shuffling and Markovianity
The behavior displayed by a quantum system when it is perturbed by a series of von Neumann measurements along time is analyzed. Because of the similarity between this general process with giving a deck of playing cards a shuffle, here it is referred to as quantum shuffling, showing that the quantum Zeno and anti-Zeno effects emerge naturally as two time limits. Within this framework, a connecti...
متن کاملIsolation and Information Flow in Quantum Dynamics
From the structure of quantum dynamics for closed and open systems, we describe several general results about information flow between interacting systems, which can be expressed in diagrammatic form. Conditions on information flow (e.g., that no information is transferred from system A to system B) imply that the overall dynamical evolution has a particular structure. We also remark that one s...

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Markovianity of Quantum Random Fields
We present a notion of quantum Markov random field based on a concept of conditional independence replacing the (usual) requirement of conditional expectation onto a desired algebra by conditional expectation onto a subalgebra, adopted to the special case that all subalgebras of the filtration are type I factors. It is immediate to introduce the classical notions like pairwise, local, global an...
