Unitary operator bases as universal averaging sets
Marcin Markiewicz, Konrad Schlichtholz
We provide a generalization of the idea of unitary designs to cover finite averaging over much more general operations on quantum states. Namely, we construct finite averaging sets…

Generalization of Gisin's Theorem to Quantum Fields
Konrad Schlichtholz, Marcin Markiewicz
We generalize Gisin's theorem on the relation between the entanglement of pure states and Bell non-classicality to the case of mode entanglement of separated groups of modes of qua…

No-go for fully unitary quantum mechanics from Bell's Theorem; comment on "Physics and Metaphysics of Wigner's Friends: Even performed pre-measurements have no results''
Konrad Schlichtholz
The purpose of this comment is to show that a reinterpretation of the results from the Letter: "Physics and Metaphysics of Wigner's Friends: Even performed pre-measurements have no…
