Comparing two cohomological obstructions for contextuality, and a generalised construction of quantum advantage with shallow circuits
We present two results on the subject of quantum contextuality and cohomology, and non-locality and quantum advantage with shallow circuits. Abramsky et al. showed that a range of examples of quantum contextuality is detected by a cohomological invariant based on Čech cohomology. However, the approa...
