Classical and quantum-mechanical phase space distributions
Thomas Kiesel
We examine the notion of nonclassicality in terms of quasiprobability distributions. In particular, we do not only ask if a specific quasiprobability can be interpreted as a classi…
Quantum Process Nonclassicality
Saleh Rahimi-Keshari, Thomas Kiesel, Werner Vogel +3
We propose a definition of nonclassicality for a single-mode quantum-optical process based on its action on coherent states. If a quantum process transforms a coherent state to a n…
Complete nonclassicality test with a photon-number resolving detector
T. Kiesel, W. Vogel
We present a method for the experimental measurement of nonclassicality witnesses and demonstrate its application. Our proposal only requires the coherent displacement of the initi…
Atomic nonclassicality quasiprobabilities
T. Kiesel, W. Vogel, S. L. Christensen +3
Although nonclassical quantum states are important both conceptually and as a resource for quantum technology, it is often difficult to test whether a given quantum system displays…
Moments of nonclassicality quasiprobabilities
Saleh Rahimi-Keshari, Thomas Kiesel, Werner Vogel
A method is introduced for the verification of nonclassicality in terms of moments of nonclassicality quasiprobability distributions. The latter are easily obtained from experiment…
Statistical analysis of sampling methods in quantum tomography
Thomas Kiesel
In quantum physics, all measured observables are subject to statistical uncertainties, which arise from the quantum nature as well as the experimental technique. We consider the st…
