Spin-coherent quantum designs
Marcin Rudziński, Aaron Z. Goldberg, Andrei B. Klimov +2
Coherent states bridge the gap between quantum and classical physics, but their overcomplete and nonorthogonal nature makes it difficult to identify the minimal discrete set needed…

Entangling power and fidelity diagnostic for bipartite quantum channels
Marcin Rudziński, Gianluigi Tartaglione, Karol Życzkowski
We study two complementary diagnostics of bipartite quantum channels, namely fidelity preservation across different classes of input states and entanglement generation from product…

Orthonormal bases of extreme quantumness
Marcin Rudziński, Adam Burchardt, Karol Życzkowski
Spin anticoherent states acquired recently a lot of attention as the most "quantum" states. Some coherent and anticoherent spin states are known as optimal quantum rotosensors. In…
