abstract

Simplicial distributions provide a framework for studying quantum contextuality, a generalization of Bell's non-locality. Understanding extremal simplicial distributions is of fundamental importance with applications to quantum computing. We introduce a rank formula for twisted simplicial distributions defined for $2$-dimensional measurement spaces and provide a systematic approach for describing extremal distributions.

  1. The geometry of simplicial distributions on suspension scenarios

    quant-ph 2024-12 conditional novelty 7.0 of 10

    For a connected measurement space X, the non-signaling polytope of the cone scenario is the join of m copies of the original polytope, and the suspension scenario is characterized by a pullback of two such joins.
