We study the dynamics of a single quark-antiquark pair in the Quark-Gluon Plasma (QGP) within the open quantum system framework. The dynamics are governed by coupled partial differential equations describing the evolution of the pair density operator in the singlet and octet color channels. We study both the charmonium and bottomonium system in one dimension, using a one-dimensional potential specifically developed for this study and tailored to capture as best as possible characteristics of a full three-dimensional potential. A first study of the suppression of bottomonia as function of the centrality, using EPOS4 temperature profiles for the QGP medium is presented.
