Contextuality for preparations, transformations, and unsharp measurements

RW Spekkens - Physical Review A—Atomic, Molecular, and Optical …, 2005 - APS
The Bell-Kochen-Specker theorem establishes the impossibility of a noncontextual hidden
variable model of quantum theory, or equivalently, that quantum theory is contextual. In this …

RW Spekkens - Foundations of Physics, 2014 - Springer
In order to claim that one has experimentally tested whether a noncontextual ontological
model could underlie certain measurement statistics in quantum theory, it is necessary to …
