Coherifying quantum channels
Kamil Korzekwa, Stanisław Czachórski, Zbigniew Puchała +1
Is it always possible to explain random stochastic transitions between states of a finite-dimensional system as arising from the deterministic quantum evolution of the system? If n…
Majorization uncertainty relations for mixed quantum states
Zbigniew Puchała, Łukasz Rudnicki, Aleksandra Krawiec +1
Majorization uncertainty relations are generalized for an arbitrary mixed quantum state of a finite size . In particular, a lower bound for the sum of two entropies characte…
Vertices cannot be hidden from quantum spatial search for almost all random graphs
Adam Glos, Aleksandra Krawiec, Ryszard Kukulski +1
In this paper we show that all nodes can be found optimally for almost all random Erdős-Rényi graphs using continuous-time quantum spatial search procedure. Thi…
Conditional entropic uncertainty relations for Tsallis entropies
Dariusz Kurzyk, Łukasz Pawela, Zbigniew Puchała
The entropic uncertainty relations are a very active field of scientific inquiry. Their applications include quantum cryptography and studies of quantum phenomena such as correlati…
Gauge invariant information concerning quantum channels
Łukasz Rudnicki, Zbigniew Puchała, Karol Zyczkowski
Motivated by the gate set tomography we study quantum channels from the perspective of information which is invariant with respect to the gauge realized through similarity of matri…
