# Optional dependencies of Qiskit that can (mostly) reliably be installed with
# `pip`.  This file is still called `requirements-optional.txt` just to match
# standard pip conventions, even though none of these are required.

# If updating this, you probably want to update `qiskit.utils.optionals` and
# maybe `pyproject.toml` too.
