SIGN UP
scqubits is an open-source Python library for simulating superconducting qubits. It is meant to give the user a convenient way to obtain energy spectra of common superconducting qubits, plot energy levels as a function of external parameters, calculate matrix elements etc. The library further provides an interface to QuTiP, making it easy to work with composite Hilbert spaces consisting of coupled superconducting qubits and harmonic modes. Internally, numerics within scqubits is carried out with the help of Numpy and Scipy; plotting capabilities rely on Matplotlib.
If scqubits is helpful to you in your research, please support its continued development and maintenance. Use of scqubits in research publications is appropriately acknowledged by citing:

For Python 3.9 - 3.12: installation via conda is supported.
conda install -c conda-forge scqubits
Alternatively, scqubits can be installed via pip (although it should be noted that installing via pip under a conda environment is strongly discouraged, and is not guaranteed to work - see conda documentation).
pip install scqubits
