Distinguishing classically indistinguishable states and channels
Kamil Korzekwa, Stanisław Czachórski, Zbigniew Puchała +1
We investigate an original family of quantum distinguishability problems, where the goal is to perfectly distinguish between quantum states that become identical under a comple…
Approximate optimization, sampling and spin-glass droplets discovery with tensor networks
Marek M. Rams, Masoud Mohseni, Daniel Eppens +2
We devise a deterministic algorithm to efficiently sample high-quality solutions of certain spin-glass systems that encode hard optimization problems. We employ tensor networks to…
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…
Quantum walks on hypergraphs
Przemysław Sadowski, Łukasz Pawela, Paulina Lewandowska +1
In this work we introduce the concept of a quantum walk on a hypergraph. We show that the staggered quantum walk model is a special case of a quantum walk on a hypergraph.
Optimal Quantum Walk Search on Kronecker Graphs with Dominant or Fixed Regular Initiators
Adam Glos, Thomas G. Wong
In network science, graphs obtained by taking the Kronecker or tensor power of the adjacency matrix of an initiator graph are used to construct complex networks. In this paper, we…
Band selection with Higher Order Multivariate Cumulants for small target detection in hyperspectral images
Przemysław Głomb, Krzysztof Domino, Michał Romaszewski +1
In the small target detection problem a pattern to be located is on the order of magnitude less numerous than other patterns present in the dataset. This applies both to the case o…
