Open Quantum Design (OQD) is a non-profit foundation supporting the development of full-stack, open-source quantum computers. OQD's current designs are based on laser-cooled trapped ion quantum computing hardware, including real-time control, backend and frontend software. This documentation covers the software components of the OQD stack, including the core programming interfaces, classical emulation backends, compiler infrastructure, and cloud server containers.
equilux is the top-level package to access the full OQD software suite in a single place.
To install equilux and the suite Open Quantum Design software tools,
pip install equiluxAlternatively, the repository can be cloned and installed locally,
git clone https://github.com/OpenQuantumDesign/equilux
pip install .Open Quantum Design's quantum computing stack can be interfaced at different levels, including the digital, analog, and atomic layers.

OQD's software stack components include Python interfaces at the digital, analog, and atomic layers, classical emulators, compiler infrastructure, and cloud server components.
Planned supported hardware backends include the Bloodstone processor based on171Yb+ ions and the Beryl processor based on133Ba+ ions.
Below is a short example of how to use the analog interface to specify, serialize, and simulate an analog quantum program - here, a single-qubit Rabi-flopping experiment.
