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…
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…
Strong Majorization Entropic Uncertainty Relations
Łukasz Rudnicki, Zbigniew Puchała, Karol Życzkowski
We analyze entropic uncertainty relations in a finite dimensional Hilbert space and derive several strong bounds for the sum of two entropies obtained in projective measurements wi…
