This Python library provides numerical tools for studying various objects in quantum information theory, namely, states, channels, and measurements. It focuses on providing computational tools to study problems about entanglement theory, nonlocal games, and matrix analysis, among other aspects of quantum information often associated with computer science. The library aims to fill the needs of quantum information researchers who want numerical tools for manipulating quantum objects. It can also be used to enhance the experience of students and instructors in quantum information classes. Examples include computing the distinguishability of quantum states and analyzing nonlocal games like the CHSH game.
