* quantum: modernize QFT to Qiskit 2.x + re-enable its test
quantum/q_fourier_transform.py used the Aer and execute symbols that were
removed from qiskit in the 1.0 API break, so it could never run and was on
the pytest --ignore list. Port it to the current API:
- Drop 'from qiskit import Aer, execute'. Build the circuit unchanged, then
simulate with the pure-Python BasicSimulator via transpile() + backend.run(),
so no compiled qiskit-aer backend is needed (qiskit-aer has no Python 3.14
wheels yet; BasicSimulator ships inside qiskit core).
- Seed the run (seed_simulator=42) and rewrite the doctest to assert the
reproducible, shot-noise-independent facts (the four outcomes appear and the
counts sum to the shot total) instead of exact per-state counts, which random
sampling can never hit.
- Add 'qiskit>=2' to project dependencies and drop the quantum ignore + the
stale '# TODO: #8818 Re-enable quantum tests' comment in build.yml.
Draft until CI confirms qiskit installs and imports on the repo's Python 3.14.
* Update quantum/q_fourier_transform.py

* pre-commit: Upgrade psf/black for stable style 2023
Updating https://github.com/psf/black ... updating 22.12.0 -> 23.1.0 for their `2023 stable style`.
* https://github.com/psf/black/blob/main/CHANGES.md#2310
> This is the first [psf/black] release of 2023, and following our stability policy, it comes with a number of improvements to our stable style…
Also, add https://github.com/tox-dev/pyproject-fmt and https://github.com/abravalheri/validate-pyproject to pre-commit.
I only modified `.pre-commit-config.yaml` and all other files were modified by pre-commit.ci and psf/black.

* create quantum_fourier_transform
This is part of the #Hacktoberfest.
I build the quantum fourier transform for N qubits. (n = 3 in the example)
Best,
Kevin
