Part of the effort to land the experimental noise model and simulation module (originally PR #1848, branch nonbreaking-noise-model) as a reviewable stack. This is PR 1 of 5; the remaining PRs stack on top of this branch and should be reviewed/merged in order. Closes #1852.

This PR raises the minimum supported Python to 3.11 (dropping 3.9/3.10), adds rigetti-quax as a dependency (the foundation the later noise-model and simulator PRs build on), and refreshes poetry.lock, the Dockerfiles, and the GitHub Actions workflows accordingly.

The bulk of the diff is mechanical typing modernization enabled by 3.11 — Optional[X]/Union[...] → X | None, collections.abc.Callable, explicit zip(..., strict=...) — plus a couple of doctest/snapshot CI stabilizations (the QASM transpile snapshot is replaced with explicit line assertions). There is no functional behavior change in this PR.

Tracked in #1863.

This looks great. Thank you for the hard work.

I think there's a mistake in the new help Makefile target, but other than that, I only had some questions/comments on some versions used in the workflows. I don't think they need to be block the PR, though.

[bramathon]

Updated rigetti-quax lower bound to 0.7.0

[bramathon]

I don't understand the OSV check failure

Looks like we should update setuptools to >=v83.0.0 to avoid this specific bug, though in our case, MANIFEST.in has no exclude rules, so it doesn't have a real impact on us.

[bramathon]

Updates setuptools to >83.0 and the checkout workflow to v7 in all locations

@asaites What should the version be set to before merge?

[asaites]

What should the version be set to before merge?

In a certain sense, it doesn't matter, because the Release workflow will run once merged, and knope will bump the version and commit the updated file. If you'd like, you can set it to v4.21.0, which is what the most recent dry-run says it would become.

The latest pyquil release on pypi is 4.17 so I thought this would be 4.18 if we increment

Oh interesting. knope does use the pyproject.toml's version number as well as the current tag values; I was under the mistaken impression it just used the tags themselves. In that case, you should set it back to 4.17.0, and knope should set it to 4.18.0.
