Abstarct: Entanglement is a characteristic of basic quantum-mechanics. This concept which was firstly mentioned in EPR essay by Einstein, Podolski, and Rojen is used to describe non-focal correlation between two or more quantum systems that such correlation is merely quantum and does not have any classical equivalent. Such kind of quantum correlation is one of the main resources of processing activities and quantum calculations. Studding entanglement states in systems applied in information and quantum calculations has been surveyed by most of the scientists. In most of quantum systems, the interaction between the system and environment (open quantum system) is unavoidable. The entanglement is highly decreased due to such interaction but in some cases the entanglement can be created or preserved in such open quantum system by considering the geometry of interaction with environment and the type of interaction. To study the dynamic of open quantum systems, the main equation (Markov or non-Markov) or super operators can be used. Quantum dots can be mentioned as favorite system in creating Qbits. To this end, the experimental construction of one Qbit can be achieved by trapping one electron in the quantum dot and controlling its interactions with other quantum dots. Meanwhile, double quantum dots along with a trapped electron within it play role as one Qbit. In this study, we firstly introduce the basic notions of quantum data and then double quantum dots, their structures, and the way of achieving to one Qbit through them are going to be discussed. Further, the quantum system is going to be discussed in more details and the main Markov equation for an open quantum system is achieved by introducing Markov dynamic. Finally, by introducing the surveyed model contained two doubled quantum dots interacting with mutual heating bath, the quantum correlation dynamic is studied by making use of basic Markov equation. In this study, the entanglement dynamic is surveyed per different initial states and in different temperatures.
