Chutes and Ladders: Dynamical Automorphisms via the ZX-Calculus
Alexander Frei, Sascha Zakaib-Bernier, Zachary Mann +2
The ZX-calculus is a powerful graphical language for manipulating quantum circuits, which has recently found many applications in quantum error correction. We extend this language…
The tilted CHSH games: an operator algebraic classification
Alexander Frei, Azin Shahiri
We introduce a general systematic procedure for solving any binary-input binary-output game using operator algebraic techniques on the representation theory for the underlying grou…
Relative Cuntz--Pimsner algebras: classification of gauge-equivariant representations: a simple and complete picture
Alexander Frei
We give a simple and complete picture on the classification of relative Cuntz--Pimsner algebras (and so also of gauge-equivariant representations) using their intuitive parametrisa…
The quantum commuting model (Ia): The CHSH game and other examples: Uniqueness of optimal states
Alexander Frei
We present in this paper that the CHSH game admits one and only one optimal state and so remove all ambiguity of representations. More precisely, we use the well-known universal de…
Connes implies Tsirelson: a simple proof
Alexander Frei
More precisely, we give a simple and very short proof of "the Connes embedding problem implies the synchronous Tsirelson conjecture" that relies on only two elementary ingredients:…
