    "abstract": "We review the standard treatment of open quantum systems in relation to\nquantum entanglement, analyzing, in particular, the behaviour of bipartite\nsystems immersed in a same environment. We first focus upon the notion of\ncomplete positivity, a physically motivated algebraic constraint on the quantum\ndynamics, in relation to quantum entanglement, i.e. the existence of\nstatistical correlations which can not be accounted for by classical\nprobability. We then study the entanglement power of heat baths versus their\ndecohering properties, a topic of increasing importance in the framework of the\nfast developing fields of quantum information, communication and computation.\nThe presentation is self contained and, through several examples, it offers a\ndetailed survey of the physics and of the most relevant and used techniques\nrelative to both quantum open system dynamics and quantum entanglement.",
