KQCircuits is a Python library developed by IQM for automating the design of superconducting quantum circuits. It uses the KLayout layout design program API.
KQCircuits generates multi-layer 2-dimensional-geometry representing common structures in quantum processing units (QPU). It includes definitions of parametrized geometrical objects or “elements”, framework to easily define your own elements, framework to get geometry from the elements by setting values to parameters and a framework to assemble a full QPU design by combining many of the elements in different geometrical relations. Among other templates, are also structures to combine QPU designs to create optical mask layout and EBL patterns for fabrication of quantum circuits and export a set of files for a mask as needed for QPU fabrication.
KQCircuits is a KLayout extension. KLayout can be used either using a graphical user interface or as a standalone python module. KQCircuits supports both modes of operation. For the first time users, the graphical user interface mode is recommended.
Install and run KLayout once. Run python3 setup_within_klayout.py then klayout will contain
KQCircuits. For further details see the getting started documentation.
For stand-alone mode run python -m pip install -e klayout_package/python[docs,tests]. Then scripts may be run and
documentation can be built. For further details see the documentation.
Documentation for KQCircuits can be found here.
It may also be generated from the sources with make html in the docs directory.
