The project is part of the theoretical work at the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, billion-SEK initiative started in 2018 with the purpose of advancing Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer. The work will consist of numerical modeling of the static properties and dynamical evolution of the superconducting circuits used for building the quantum computer, focusing on particular operations like quantum gates, readout or qubit reset. To support this simulations, we have developed a software package for simulating the superconducting qubits (Chalmers Superconducting Qubit Repository, CSQR, more on its technical details under "Resource Usage"). It has been developed at Chalmers University of Technology, and it is playing a bigger and bigger role in the simulations used to inform design and analyze the behavior of the qubits in the main WACQT project of developing a 100-qubit superconducting quantum computer. The jobs run in the cluster will thus be numerical simulations using CSQR that can more or less be organized in three kinds of tasks: (1) inform the experimental work on the quantum computer, (2) provide numerical support to test theoretical ideas developed by the modelling group at WACQT, (3) help with the development of CSQR itself.
