Towards higher precision and operational use of optical homodyne tomograms
M. Bellini, A. S. Coelho, S. N. Filippov +2
We present the results of an operational use of experimentally measured optical tomograms to determine state characteristics (purity) avoiding any reconstruction of quasiprobabilit…
Simulation of indivisible qubit channels in collision models
Tomas Rybar, Sergey N. Filippov, Mario Ziman +1
A sequence of controlled collisions between a quantum system and its environment (composed of a set of quantum objects) naturally simulates (with arbitrary precision) any Markovian…
Probability-based comparison of quantum states
Sergey N. Filippov, Mario Ziman
We address the following state comparison problem: is it possible to design an experiment enabling us to unambiguously decide (based on the observed outcome statistics) on the same…
