We show, under natural assumptions for qubit systems, that measurement-based quantum computations (MBQCs) which compute a non-linear Boolean function with high probability are contextual. The class of contextual MBQCs includes an example which is of practical interest and has a super-polynomial speedup over the best known classical algorithm, namely the quantum algorithm that solves the Discrete Log problem.

  1. Genuine Global Kochen-Specker Contextuality as Classical Coordination Cost

    quant-ph 2026-06 unverdicted novelty 7.0

    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.
