Decoherence is an unavoidable phenomenon that results from the interaction of the system with its surroundings. The study of decoherence due to the relativistic effects has the fundamental importance. The Unruh effect is observed by the relativistically accelerator observer. The unruh effect can be considered as a quantum channel called Unruh channel. The Unruh channel can be characterized by its Kraus representation. We consider the bipartite scheme in which the quantum information is shared between an inertial observer (Alice) and an accelerated observer (Rob) in the case of Dirac field. We will show that this channel reduces the common quantum information between the two observers. In this work we will study the effects of the Unruh channel on various facets of quantum correlations, such as the quantum teleportation, entanglement, and Bell inequality violations for a Dirac field mode.

退相干是系统与周围环境相互作用所导致的不可避免的现象。研究相对论效应引起的退相干具有根本的重要性。相对论加速器观察者观察到了Unruh效应。Unruh效应可以视为称为Unruh通道的量子通道。Unruh频道可以通过其Kraus表示来表征。我们考虑二分方案，其中在狄拉克场的情况下，惯性观测器（Alice）和加速观测器（Rob）之间共享量子信息。我们将显示该通道减少了两个观察者之间的公共量子信息。在这项工作中，我们将研究Unruh通道对量子相关性各个方面的影响，例如量子隐形传态，纠缠，
