We present a bipartite two-level system coupled to electromagnetic quantum vacuum fluctuations through ageneral dipolar coupling. We derive the master equation in the framework of an open quantum system, assumingan environment composed of (i) solely vacuum fluctuations and (ii) the vacuum fluctuations and a conductingplate located at a fixed distance from the bipartite system. For both cases considered, we study the dynamicsof the bipartite system and the temporal evolution of the concurrence of an initial entangled bipartite state.We further analyze the generation of entanglement due to the vacuum structure. Finally, we study the differentinduced contributions to the correction of the unitary geometric phase of a bipartite quantum state so as to explorethe possibility of future experimental setups by exploring the influence of boundaries conditions in vacuum.
