One motivation behind our research work is to find Other ways to study the problem of a quantum theory of gravitation. Another motivation is to develop some new techniques to tackle the problem of the quantum information processing in realistic situations and formulate experimental devices for this purpose. In order to identify a conceptual approach for our objective, a conceptual discussion about the two physical theories that conform the background for our physical system, is presented throughout the di\_erent chapters in the text. Finally we present the main results of this research work where we examine the entanglement generation between uniformly accelerated two-level atoms weakly coupled with a massless scalar field in Minkowski vacuum. We investigate this phenomenon in the framework of time-dependent perturbation theory. We evaluate a finite-time response function and we identify the mutual inuence of atoms via the quantum field as a coherence agent in each response function terms. The associated thermal spectrum perceived by the atoms is found for a long observational time interval. In addition, we study the mean life of entangled states for diferent accelerations. The possible relevance of our results is discussed. ## **Datos de la publicación**
