Welcome! This notebook serves as a top-level "readme" document for pyGSTi. It and the other notebooks in this directory describe and demonstrate how you can use the
pygsti package to accomplish various tasks related to quantum characterization. We'll start with a brief general introduction and then move on to specifics.
PyGSTi is a Python framework for modeling and analyzing collections of qubits, more affectionately called quantum information processors (QIPs). We use "QIP" generously to include systems of just 1 or 2 qubits in addition to larger systems. Initially pyGSTi was developed to perform a single type of data analysis called Gate Set Tomography (GST), from where pyGSTi derives it's name. While GST is still a central capability of the package, pyGSTi is capable of modeling QIP behavior and analyzing QIP data much more generally.
For example, some things you might use pyGSTi for are:
This documentation facilitates two basic approaches to getting started with pyGSTi. The first is a bottom-up approach, which starts by introducing the main components of pyGSTi and how they work together, and then explains what you can do with them. If you like this approach or are ambivalent, you should read through these two notebooks to get a high-level overview of what pyGSTi can do:
(These notebooks contain links to other notebooks covering more advanced functionality that you are free to explore as desired.)
The second approach is a top-down approach. If you have a particular problem you need solved and you want to know what 5 lines of Python code will get it done for you, then you should visit the FAQ and with links to associated example notebooks. If your question isn't answered there, you should email us at [email protected] or add an issue to the pyGSTi github page.
