This code calculates the eigensystem of the Jaynes-Cummings ladder of a multi-level qubit (e.g., transmon) and its readout resonator. The resulted eigenenergies can be used to calculate interesting quantities that are usefull for understanding the dispersive measurement.
For a detailed discussion of the system, parameters and meaning of jargons used here see Phys. Rev. A 94, 012347 (2016) and Phys. Rev. Lett. 117, 190503 (2016). If you use this code in your project, please consider citing these papers.
Please refer to examples.ipynb jupyter notebook to see how the code can be used.
