Classical simulation of universal measurement-based quantum computation using multipartite Bell scenarios

Cihan Okay, Atak Talay Yucel, Selman Ipek

We introduce a new classical simulation algorithm based on non-signaling polytopes of multipartite Bell scenarios, capable of simulating universal measurement-based quantum computa…

Twisted simplicial distributions

Cihan Okay, Walker H. Stern

We introduce a theory of twisted simplicial distributions on simplicial principal bundles, which allow us to capture Bell's non-locality, and the more general notion of quantum con…

The operadic theory of convexity

Redi Haderi, Cihan Okay, Walker H. Stern

In this article, we characterize convexity in terms of algebras over a PROP, and establish a tensor-product-like symmetric monoidal structure on the category of convex sets. Using…

Equivariant simplicial distributions and quantum contextuality

Cihan Okay, Igor Sikora

We introduce an equivariant version of contextuality with respect to a symmetry group, which comes with natural applications to quantum theory. In the equivariant setting, we const…

A bundle perspective on contextuality: Empirical models and simplicial distributions on bundle scenarios

Rui Soares Barbosa, Aziz Kharoof, Cihan Okay

This paper provides a bundle perspective to contextuality by introducing new categories of contextuality scenarios based on bundles of simplicial complexes and simplicial sets. The…

Simplicial techniques for operator solutions of linear constraint systems

Ho Yiu Chung, Cihan Okay, Igor Sikora

A linear constraint system is specified by linear equations over the group $\ZZ_d$ of integers modulo . Their operator solutions play an important role in the study of quantum c…
