Generating random quantum channels
Ryszard Kukulski, Ion Nechita, Łukasz Pawela +2
Several techniques of generating random quantum channels, which act on the set of -dimensional quantum states, are investigated. We present three approaches to the problem of sa…
On the optimal certification of von Neumann measurements
Paulina Lewandowska, Aleksandra Krawiec, Ryszard Kukulski +2
In this report we study certification of quantum measurements, which can be viewed as the extension of quantum hypotheses testing. This extension involves also the study of the inp…
Log-Convex set of Lindblad semigroups acting on -level system
Fereshte Shahbeigi, David Amaro-Alcalá, Zbigniew Puchała +1
We analyze the set of mixed unitary channels represented in the Weyl basis and accessible by a Lindblad semigroup acting on an -level quantum system. General nece…
Discrimination of POVMs with rank-one effects
Aleksandra Krawiec, Łukasz Pawela, Zbigniew Puchała
The main goal of this work is to provide an insight into the problem of discrimination of positive operator valued measures with rank-one effects. It is our intention to study mult…
