usel 1.0.4

An open-source, CPU-only scientific computing framework focused on quantum physics simulations and numerical methods.

USEL

USEL () is an open-source, CPU-only scientific computing framework focused on quantum physics simulations and numerical methods.

Version 1.0 establishes the mathematical and computational foundation — matrix and linear algebra utilities, numerical solvers, FFT-based frequency analysis, random number generation, configuration/IO/logging utilities, and a CLI — for future quantum mechanics, computational physics, and quantum information modules.

Features

• Runs efficiently on standard consumer hardware, no GPU required
• Operates within 8 GB RAM
• Cross-platform (Windows, Linux, macOS)
• Modular, extensible architecture
• Fully typed, PEP 8 compliant codebase

Installation

uv sync
uv run usel version

Or, for local development:

git clone https://github.com/usel/usel.git
cd usel
uv sync --group dev

See the examples directory for more, including eigenvalue solving, ODE integration, FFT analysis, and numerical integration.

Command Line Interface

uv run usel version
uv run usel doctor
uv run usel benchmark --size 200
uv run usel info
uv run usel config path/to/config.yaml
uv run usel test

Non-Goals (v1.0)

This release intentionally excludes the Schrödinger equation, quantum circuits/gates/qubits, machine learning, chemistry simulation, GPU/cloud computing, and AI integration. These are planned for future releases (see CHANGELOG.md and the roadmap below).

Roadmap

• v1.0 — Scientific Computing Foundation

  • Core numerical engine
  • Linear algebra utilities
  • Matrix operations
  • Numerical solvers
  • FFT and mathematical utilities
  • Configuration, logging, and CLI support

• v2.0 — Quantum Physics Engine

  • Schrödinger equation module
  • Quantum wavefunction utilities
  • Potential models
  • Hamiltonian construction
  • Time evolution and visualization

• v3.0 — Relativistic & Computational Physics

  • Dirac equation module
  • Spinor algebra
  • Gamma matrix operations
  • Relativistic particle simulations
  • Maxwell equation module
  • Electromagnetic field simulations

Still more planning is going on this.
