Linking Quantum Discord to Entanglement in a Measurement
Alexander Streltsov, Hermann Kampermann, Dagmar Bruß
We show that a von Neumann measurement on a part of a composite quantum system unavoidably creates distillable entanglement between the measurement apparatus and the system if the…
Experimentally implementable criteria revealing substructures of genuine multipartite entanglement
Marcus Huber, Hans Schimpf, Andreas Gabriel +3
We present a general framework that reveals substructures of genuine multipartite entanglement. Via simple inequalities it is possible to discriminate different sets of multipartit…
Min-entropy and quantum key distribution: non-zero key rates for "small" numbers of signals
Sylvia Bratzik, Markus Mertz, Hermann Kampermann +1
We calculate an achievable secret key rate for quantum key distribution with a finite number of signals, by evaluating the min-entropy explicitly. The min-entropy can be expressed…
