QGeo: A Python package for calculating geodesic control functions for quantum computing

Quantum Physics 2025-04-24 v1

Abstract

We present a new Python package that uses the established notion of geometric quantum complexity to numerically compute the difficulty associated with preparing a given unitary transformation on a quantum computer. The numerical procedure we implement is presented and discussed. Analyzed quantum circuits include: the quantum fourier transform for up to four qubits, a random circuit with depth 100, and a circuit for analyzing the evolution of a fermionic chain with several lattice sites. This package can be found for download at https://github.com/JAGDiaz/quantum-geodesics
