Revealing quantum properties with simple measurements
S. Wölk
Since the beginning of quantum mechanics, many puzzling phenomena which distinguish the quantum from the classical world, have appeared such as complementarity, entanglement or con…
Generalized Effective Operator Formalism for Decaying Systems
Marius Paraschiv, Sabine Wölk, Thomas Mannel +1
Systems of neutral kaons can be used to observe entanglement and the violation of Bell inequalities. The decay of these particles poses some problems, however, and recently an effe…
Optimized parameter estimation in the presence of collective phase noise
Sanah Altenburg, Sabine Wölk, Geza Toth +1
We investigate phase and frequency estimation with different measurement strategies under the effect of collective phase noise. First, we consider the standard linear estimation sc…
A unified approach to entanglement criteria using the Cauchy-Schwarz and Hölder inequalities
Sabine Wölk, Marcus Huber, Otfried Gühne
We present unified approach to different recent entanglement criteria. Although they were developed in different ways, we show that they are all applications of a more general prin…
