Combining contextuality and causality: a game semantics approach
We develop an approach to combining contextuality with causality, which is
general enough to cover causal background structure, adaptive measurement-based
quantum computation, and causal networks. The key idea is to view contextuality
as arising from a game played between Experimenter and Nature, allowing for
causal dependencies in the actions of both the Experimenter (choice of
measurements) and Nature (choice of outcomes).Comment: 13 page
The Road to Quantum Computational Supremacy
We present an idiosyncratic view of the race for quantum computational
supremacy. Google's approach and IBM challenge are examined. An unexpected
side-effect of the race is the significant progress in designing fast classical
algorithms. Quantum supremacy, if achieved, won't make classical computing
obsolete.Comment: 15 pages, 1 figur
