Automate the design of superconducting quantum circuits.
KQCircuits is a Python library developed by the Aalto University and IQM Quantum Computers 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.
Multi Qubit QPUs are a central part of Quantum Computers. Elements in KQCircuits are fully parameterised, to quickly design chips. Full access of the library of Quantum processor from IQM.
Quantum processor design is integral to the advancement of quantum innovation, but it is a difficult, time consuming process that involves several repetitive tasks.
KQCircuits using automation and reusable processes provides a scalable solution. Our vision is to develop a community-driven universal platform capable of orchestrating quantum chip development from concept to fabrication in a simple and open framework.
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 .[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.
