A Unified Linear Algebraic Framework for Physical Models and Generalized Contextuality
Farid Shahandeh, Theodoros Yianni, Mina Doosti
We develop a bottom-up, statistics-first framework in which the full probabilistic content of an operational theory is encoded in its matrix of conditional outcome probabilities of…

Complexity of Contextuality
Theodoros Yianni, Farid Shahandeh
Generalized contextuality is a hallmark of nonclassical theories like quantum mechanics. Yet, three fundamental computational problems concerning its decidability and complexity re…
