paulie 0.0.2

Classification of Pauli Lie algebras

PauLie

The PauLie package is an open-source library for studying various algebraic properties of quantum circuits. This first release focuses on the classification of the circuit's dynamical Lie algebra given the generators as Pauli strings.

Installation

PauLie package requires Python 3.12 or newer. To install PauLie, run:

pip install paulie

Getting started

The following code gives an example of usage:

    from paulie import get_pauli_string as p
    
    n_qubits = 6
    generators = p(["XYZX", "ZZYZY"], n = n_qubits)
    algebra = generators.get_algebra()
    print(f"number of qubits = {n_qubits}, algebra = {algebra}")
