Quantifying channels output similarity with applications to quantum control
Łukasz Pawela, Zbigniew Puchała
In this work we aim at quantifying quantum channel output similarity. In order to achieve this, we introduce the notion of quantum channel superfidelity, which gives us an upper bo…
Asymptotic entropic uncertainty relations
Radosław Adamczak, Rafał Latała, Zbigniew Puchała +1
We analyze entropic uncertainty relations for two orthogonal measurements on a -dimensional Hilbert space, performed in two generic bases. It is assumed that the unitary matrix…
Central limit theorem for reducible and irreducible open quantum walks
Przemysław Sadowski, Łukasz Pawela
In this work we aim at proving central limit theorems for open quantum walks on . We study the case when there are various classes of vertices in the network. Further…
Real numerical shadow and generalized B-splines
Charles F. Dunkl, Piotr Gawron, Łukasz Pawela +2
Restricted numerical shadow of an operator of order is a probability distribution supported on the numerical range restricted to a certain subset of…
Diagonal unitary entangling gates and contradiagonal quantum states
Arul Lakshminarayan, Zbigniew Puchała, Karol Życzkowski
Nonlocal properties of an ensemble of diagonal random unitary matrices of order are investigated. The average Schmidt strength of such a bipartite diagonal quantum gate is sh…
Generalized open quantum walks on Apollonian networks
Ł. Pawela, P. Gawron, J. A. Miszczak +1
We introduce the model of generalized open quantum walks on networks using the Transition Operation Matrices formalism. We focus our analysis on the mean first passage time and the…
