摘要：

Quantum entanglement is at the heart of quantum information processing. Various methods for the detection of entanglement have been developed. Here, we will explain an approach that uses locally non-effective unitary operations which, however, do cause a change of the global density matrix - an indication for the existence of correlations. We investigate whether this method can distinguish between classical and quantum correlations.
