Contextuality in Sequential State Discrimination
Nyan Raess, Farid Shahandeh
Generalized contextuality is known to be required in optimal strategies for quantum state discrimination protocols. More recently, sequential discrimination tasks have been studied…
Linear Algebra of Generalized Contextuality in All Prepare-Transform-Measure Scenarios
Theodoros Yianni, Nyan Raess, Farid Shahandeh
Generalized contextuality is a canonical distinguishing property of nonclassical generalized probabilistic theories, in particular quantum mechanics. Methods for certification and…
Sheaf-Theoretic Preparation Contextuality
Tom Williams, Mina Doosti, Farid Shahandeh
We introduce a preparation-dual notion of contextuality, formulated as an obstruction to stochastic extension. In parallel with the sheaf-theoretic formulation of measurement conte…
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…
Contextuality of all optimal quantum cloning
Mina Doosti, Theodoros Yianni, Farid Shahandeh
Quantum contextuality is a key nonclassical feature underlying advantages in quantum computation and communication. We introduce a new method to study contextuality in quantum info…
Quantum Hypercube States
L. A. Howard, T. J. Weinhold, F. Shahandeh +4
We introduce quantum hypercube states, a class of continuous-variable quantum states that are generated as orthographic projections of hypercubes onto the quadrature phase-space of…
