Distances between pure quantum states induced by a distance matrix
Tomasz Miller, RafaÅ BistroÅ
With the help of a given distance matrix of size , we construct an infinite family of distances (where ) on the complex projective space $\mathbb{P}(\mathbb{C}^n…
Absolutely maximally entangled pure states of multipartite quantum systems
Grzegorz Rajchel-MieldzioÄ, RafaÅ BistroÅ, Albert Rico +2
Absolutely maximally entangled (AME) pure states of a system composed of parties are distinguished by the property that for any splitting at least one partial trace is maximall…
Graph restricted tensors: building blocks for holographic networks
Rafaĺ BistroÅ, Márton Mestyán, Balázs Pozsgay +1
We analyze few-body quantum states with particular correlation properties imposed by the requirement of maximal bipartite entanglement for selected partitions of the system into tw…
Benchmarking quantum devices beyond classical capabilities
RafaÅ BistroÅ, Rafał Bistroń, Marcin RudziÅski +4
Rapid development of quantum computing technology has led to a wide variety of sophisticated quantum devices. Benchmarking these systems becomes crucial for understanding their cap…
Quantum convolutional channels and multiparameter families of 2-unitary matrices
RafaÅ BistroÅ, Jakub Czartowski, Karol Å»yczkowski
Many alternative approaches to construct quantum channels with large entangling capacity were proposed in the past decade, resulting in multiple isolated gates. In this work, we pu…
Product Weyl-Heisenberg covariant MUBs and Maximizers of Magick
Bogdan S. Damski, RafaÅ BistroÅ, Diego Ponterio +2
In this work we investigate discrete structures in product Hilbert spaces. For monopartite systems of size one relies on the Weyl-Heisenberg group , while in the case of…
