name: Wheel::Linux::x86_64::CUDA

# **What it does**: Builds python wheels for Linux (ubuntu-latest) architecture x86_64 and store it as artifacts.
#                   Python versions: 3.9, 3.10, 3.11, 3.12.
# **Why we have it**: To build wheels for pennylane-lightning-gpu installation.
# **Who does it impact**: Wheels to be uploaded to PyPI.
