Process reconstruction from incomplete and/or inconsistent data
Mario Ziman, Martin Plesch, Vladimir Buzek
We analyze how an action of a qubit channel (map) can be estimated from the measured data that are incomplete or even inconsistent. That is, we consider situations when measurement…
Realization of POVMs using measurement-assisted programmable quantum processors
Mario Ziman, Vladimir Buzek
We study possible realizations of generalized quantum measurements on measurement-assisted programmable quantum processors. We focus our attention on the realization of von Neumann…
Description of quantum dynamics of open systems based on collision-like models
Mario Ziman, Peter Stelmachovic, Vladimir Buzek
Master equations in the Lindblad form describe evolution of open quantum systems that is completely positive and simultaneously has a semigroup property. We analyze a possibility t…
Reconstruction of superoperators from incomplete measurements
Mario Ziman, Martin Plesch, Vladimir Buzek
We present strategies how to reconstruct (estimate) properties of a quantum channel described by the map E based on incomplete measurements. In a particular case of a qubit channel…
