Discrimination and certification of unknown quantum measurements
Aleksandra Krawiec, Łukasz Pawela, Zbigniew Puchała
We study the discrimination of von Neumann measurements in the scenario when we are given a reference measurement and some other measurement. The aim of the discrimination is to de…
Excluding false negative error in certification of quantum channels
Aleksandra Krawiec, Łukasz Pawela, Zbigniew Puchała
Certification of quantum channels is based on quantum hypothesis testing and involves also preparation of an input state and choosing the final measurement. This work primarily foc…
Space-efficient binary optimization for variational computing
Adam Glos, Aleksandra Krawiec, Zoltán Zimborás
In the era of Noisy Intermediate-Scale Quantum (NISQ) computers it is crucial to design quantum algorithms which do not require many qubits or deep circuits. Unfortunately, the mos…
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…
Asymptotic entropy of the Gibbs state of complex networks
Adam Glos, Aleksandra Krawiec, Łukasz Pawela
In this work we study the entropy of the Gibbs state corresponding to a graph. The Gibbs state is obtained from the Laplacian, normalized Laplacian or adjacency matrices associated…
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…
Multiple-shot and unambiguous discrimination of von Neumann measurements
Zbigniew Puchała, Łukasz Pawela, Aleksandra Krawiec +2
We present an in-depth study of the problem of multiple-shot discrimination of von Neumann measurements in finite-dimensional Hilbert spaces. Specifically, we consider two scenario…
Strategies for optimal single-shot discrimination of quantum measurements
Zbigniew Puchała, Łukasz Pawela, Aleksandra Krawiec +1
In this work we study the problem of single-shot discrimination of von Neumann measurements, which we associate with measure-and-prepare channels. There are two possible approaches…
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…
