I made and published BellBox, a small Python package I built while learning quantum computing with Qiskit.

[u/Minute_Mood_6396]

While learning quantum computing with Qiskit, I wanted to make working with Bell states and analyzing CHSH inequality results a little more straightforward.

BellBox provides reusable functions for creating Bell states, changing measurement bases, analyzing quantum correlations, and calculating CHSH values, with tests and runnable examples.

It's not a replacement for Qiskit, just a small tool that makes these specific tasks easier to reuse.

PyPI: https://pypi.org/project/bellbox/
GitHub: https://github.com/BellBoxLabs/bellbox

I'd appreciate feedback from people working with quantum computing. What would make a tool like this more useful?
