A mathematical framework for operational fine tunings

Catani, Lorenzo, Leifer, Matthew

Understand

In the framework of ontological models, the inherently nonclassical features of quantum theory always seem to involve properties that are fine tuned, i.e.

  • properties that hold at the operational level but break at the ontological level.
  • Their appearance at the operational level is due to unexplained special choices of the ontological parameters, which is what we mean by a fine tuning.
  • Famous examples of such features are contextuality and nonlocality.
