- Title: Contextuality, Fine-Tuning, and Teleological Explanation
- Authors: Emily Adlam
- Abstract summary: I argue that contextuality is best thought of in terms of fine-tuning.
This behaviour can be understood as a manifestation of teleological features of physics.
I show that measurement contextuality can be explained by appeal to a global constraint forbidding closed causal loops.

- Abstract: I assess various proposals for the source of the intuition that there is
something problematic about contextuality, ultimately concluding that
contextuality is best thought of in terms of fine-tuning. I then argue that as
with other fine-tuning problems in quantum mechanics, this behaviour can be
understood as a manifestation of teleological features of physics. Finally I
discuss several formal mathematical frameworks that have been used to analyse
contextuality and consider how their results should be interpreted by
scientific realists. In the course of this discussion I obtain several new
mathematical results - I demonstrate that preparation contextuality is a form
of fine-tuning, I show that measurement contextuality can be explained by
appeal to a global constraint forbidding closed causal loops, and I demonstrate
how negative probabilities can arise from a classical ontological model
together with an epistemic restriction.

Experiments [1.1650821883155187]
Contextuality is a feature of quantum correlations.
It is crucial from a foundational perspective as a nonclassical phenomenon, and from an applied perspective as a resource for quantum advantage.
We prove the continuity of a known measure of contextuality, the contextual fraction, which ensures its robustness to noise.
We then bound the extent to which these relaxations can account for contextuality, culminating in a notion of genuine contextuality, which is robust to experimental imperfections.
