Preparation Contextuality Powers Parity-Oblivious Multiplexing
Preparation Contextuality Powers Parity-Oblivious Multiplexing
In a noncontextual hidden variable model of quantum theory, hidden variables determine the outcomes of every measurement in a manner that is independent of how the measurement is implemented. Using a generalization of this notion to arbitrary operational theories and to preparation procedures, we demonstrate that a particular two-party information-processing …
