Quaternions Python Packages

ahrs

Attitude and Heading Reference Systems in Python

hypercomplex-engine

A modular engine designed for hypercomplex number generation and high-dimensional algebraic computations.

clifford

Geometric Algebra for Python

rqm-qiskit

Repository name: rqm-qiskit Mission: Build a clean, production-ready Python package that provides an SU(2)-native / quaternion-inspired interface on top of Qiskit, so users can describe 1-qubit quantum states and gates in rotation-first geometric language, then convert them into standard Qiskit circuits for simulation and IBM Quantum execution

galgebra

Symbolic Geometric Algebra/Calculus package for SymPy :crystal_ball:

gem

A lightweight, pure-Python library for graphics, geometry, and computational mathematics. No NumPy or compiled extensions.

rqm-optimize

SU(2)-aware circuit compression for quantum workflows

quat-numpy

Quaternion algebra library with vector/matrix/tensor collections, linear algebra (SVD), interpolation (SLERP/squad), signal processing (QFFT/QConv), and optimized einsum kernels.

tf-quat2rot

:triangular_ruler: Numerically stable conversion between quaternion and rotation matrices in tensorflow.

tfquaternion

A differentiable quaternion implementation in tensorflow.

pyquat

Python C quaternion type for fast attitude and rotation computations

quaternion-monoid-algebra

Compositional algebra over fixed-width quaternionic-symbolic state packets: a closed associative binary operation with two-sided identity, on CPU and GPU.

spinstep

Quaternion-based orientation control and traversal in observer-centered spherical coordinates.
