Abstract

Entanglement verification is a tool for testing quantum sources and quantum devices, which are to use in quantum information processing and quantum communication applications. Despite a quite considerable effort in developing both theoretical and experimental tools for reliable entanglement verification, there is still a big demand for better matching of theoretical models and experimental reality. In this talk I will report on recent work into two different directions. First, I will consider entanglement detection based merely on the dimension of the underlying quantum state, providing therefore a theoretical technique, which is robust against systematic errors. Second, I will present a method for improving entanglement verification based on the data from the entanglement witness experiments.
