QI

QI is a package for Mathematica computer algebra system developed to support symbolic analysis of quantum states and operations.

Usage

Package funcionality is defined in QI.m, QIExtras.m, QINisq, and QIWalks files, whish should be placed in Applications subdirectory in .Mathematica directory (on Unix-based systems).

The main package can be loaded

<<QI`

Less common functionality is available in QIExtras package

<<QIExtras`

Functions relevant for NISQ computing are available in QINisq package.

<<QINisq`

Basic functionality for simulating unitary quantum walks is are available in QIWalks package.

<<QIWalks`

Documentation

Documentation, including description of all functions, is available in doc subdirectory.
