Memory cost for simulating all quantum correlations of the Peres-Mermin scenario
read the original abstract
Sequences of compatible quantum measurements can be contextual and any simulation with a classical model accounting for the quantum observations, needs to use some internal memory. In Ref. [New J. Phys. 13, 113011 (2011)], it was shown that simulating the sequences of compatible observables from the Peres-Mermin scenario requires at least three different memory states in order to be not in contradiction with the deterministic predictions of quantum theory. We extend this analysis to the probabilistic quantum predictions and ask how much memory is required to simulate the quantum correlations generated by any quantum state. We find, that even in this comprehensive approach only three internal states are required for the perfect simulation of the quantum correlations in the Peres-Mermin scenario.

Genuine Global Kochen-Specker Contextuality as Classical Coordination Cost
Genuine global KS contextuality is framed as the classical coordination cost needed to maintain a global noncontextual explanation from locally available information in multipartite systems.
