Memory cost of quantum contextuality
read the original abstract
The simulation of quantum effects requires certain classical resources, and quantifying them is an important step in order to characterize the difference between quantum and classical physics. For a simulation of the phenomenon of state-independent quantum contextuality, we show that the minimal amount of memory used by the simulation is the critical resource. We derive optimal simulation strategies for important cases and prove that reproducing the results of sequential measurements on a two-qubit system requires more memory than the information carrying capacity of the system.

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.
