Reference designs
=================

Complete designs to copy and adapt, from a single unit cell to a chip with simulation. Reproductions of published devices are on the :doc:`../research` page; the 100-qubit mockup is tutorial :doc:`2.22 <../tut/2-From-components-to-chip/2.22-Design-100-qubits-programmatically>`.

Unit cells
----------

Reference layouts from stock Quantum Metal components. A.1-A.3 are adapted with attribution from the open-source `SQDMetal <https://github.com/sqdlab/SQDMetal>`_ benchmark devices (`arXiv:2511.01220 <https://arxiv.org/abs/2511.01220>`_).
