Choi-level twirling of quantum channels: finite constructions and non-compact transformations
Marcin Markiewicz, Åukasz Pawela, Łukasz Pawela +2
Twirling, i.e. averaging over symmetry actions, is a standard tool for reducing quantum states and channels to a symmetry-invariant form. We study channel twirling from the perspec…
Matrix logistic map: fractal spectral distributions and transfer of chaos
Åukasz Pawela, Karol Å»yczkowski
The standard logistic map, , serves as a paradigmatic model to demonstrate how apparently simple non-linear equations lead to complex and chaotic dynamics. In this work…
Local certification of unitary operations
Ryszard Kukulski, Mateusz Stępniak, Mateusz StÄpniak +7
In this work, we analyze the local certification of unitary quantum channels, which is a natural extension of quantum hypothesis testing. A particular case of a quantum channel ope…
Hybrid quantum-classical computation for automatic guided vehicles scheduling
Tomasz Åmierzchalski, Jakub PawÅowski, Artur Przybysz +6
Motivated by recent efforts to develop quantum computing for practical, industrial-scale challenges, we demonstrate the effectiveness of state-of-the-art hybrid (not necessarily qu…
