Absolutely maximally entangled pure states of multipartite quantum systems
Grzegorz Rajchel-Mieldzioć, Rafał Bistroń, 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…
Quantum Circuits for High-Dimensional Absolutely Maximally Entangled States
Berta Casas, Grzegorz Rajchel-Mieldzioć, Suhail Ahmad Rather +4
Absolutely maximally entangled (AME) states of multipartite quantum systems exhibit maximal entanglement across all possible bipartitions. These states lead to teleportation protoc…
Quantum Resource Theories beyond Convexity
Roberto Salazar, Jakub Czartowski, Ricard Ravell Rodríguez +3
A class of quantum resource theories, based on non-convex star-shape sets, presented in this work captures the key quantum properties that cannot be studied by standard convex theo…
Rényi-Holevo inequality from --Rényi relative entropies
Diego G. Bussandri, Grzegorz Rajchel-Mieldzioć, Pedro W. Lamberti +1
We investigate bounds in the transmission of classical information through quantum systems. Our focus lies in the generalized Holevo theorem, which provides a single-letter Holevo-…
Multi-Unitary Complex Hadamard Matrices
Wojciech Bruzda, Grzegorz Rajchel-Mieldzioć, Karol Życzkowski
We analyze the set of real and complex Hadamard matrices with additional symmetry constrains. In particular, we link the problem of existence of maximally entangled multipartite st…
Operation fidelity explored by numerical range of Kraus operators
Igor Chełstowski, Grzegorz Rajchel-Mieldzioć, Karol Życzkowski
Present-day quantum devices require precise implementation of desired quantum channels. To characterize the quality of implementation one uses the average operation fidelity , d…
Quantum mappings and designs
Grzegorz Rajchel-Mieldzioć
In order to use quantum devices for computations, it is necessary to understand the intricacies of the theoretical description. To this end, we provide several novel constructions…
Genuinely quantum SudoQ and its cardinality
Jerzy Paczos, Marcin Wierzbiński, Grzegorz Rajchel-Mieldzioć +2
We expand the quantum variant of the popular game Sudoku by introducing the notion of cardinality of a quantum Sudoku (SudoQ), equal to the number of distinct vectors appearing in…
