Quantum Fuzzy Inference Engine

QFIE is a Python package for building and executing Quantum Fuzzy Inference Engines. It implements the approach introduced in On the Implementation of Fuzzy Inference Engines on Quantum Computers.

Installation

QFIE requires Python 3.10 or later. Install the package from PyPI with:

pip install QFIE

To install the latest development version directly from the repository:

pip install "git+https://github.com/Quasar-UniNA/QFIE.git"

The complete user guide and examples are available in the QFIE documentation.
