QMix

Quantum Mixing software

PyPI version ci flake8 License: GPL v3

QMix is used to simulate the quasiparticle tunneling currents in Superconductor/Insulator/Superconductor (SIS) junctions. In radio astronomy, these junctions are used for heterodyne mixing at millimeter and submillimeter wavelengths. QMix can be used to simulate the behavior of SIS mixers, optimize their performance and analyze experimental data.

In order to calculate the quasiparticle tunneling currents, QMix uses multi-tone spectral domain analysis (see references). Among other applications, this makes QMix ideal for simulating power saturation, higher-order harmonics, sub-harmonic pumping, harmonic mixing and frequency multiplication.

Getting Started

The easiest way to install QMix is using pip:

```bash

for latest release (from PyPI)

python -m pip install QMix

for latest commit (from GitHub)

python -m pip install git+https://github.com/garrettj403/QMix.git ```

Take a look at the QMix website for more information on how to use the QMix package and examples showing how to simulate SIS junctions. If you run into any problems, please create a new issue through the issue tracker with the help wanted or question tag. In your message, make sure to include your operating system, Python version, and package versions for QMix, Numpy, SciPy and Matplotlib.
