Entanglement Distillation using the Exchange Interaction
Adrian Auer, René Schwonnek, Christian Schoder +3
A key ingredient of quantum repeaters is entanglement distillation, i.e., the generation of high-fidelity entangled qubits from a larger set of pairs with lower fidelity. Here, we…

Uncertainty Relations for Angular Momentum
Lars Dammeier, René Schwonnek, Reinhard F. Werner
In this work we study various notions of uncertainty for angular momentum in the spin-s representation of SU(2). We characterize the "uncertainty regions'' given by all vectors, wh…
