# toqito: Theory of Quantum Information Toolkit
The `toqito` package is an open-source Python library for studying various
objects in quantum information, namely, states, channels, and measurements.
Specifically, `toqito` focuses on providing numerical tools to study problems
about entanglement theory, nonlocal games, matrix analysis, and other
aspects of quantum information that are often associated with computer science.
`toqito` aims to fill the needs of quantum information researchers who want
numerical and computational tools for manipulating quantum states,
measurements, and channels. It can also be used as a tool to enhance the
experience of students and instructors in classes about quantum
information.
## Getting Started
toqito is available via [PyPi](https://pypi.org/project/toqito/) for Linux, and macOS, with support for Python 3.10 to 3.12.
```console
(venv) $ pip install toqito
```
The following code gives an example on the usage:
```python
# Calculate the classical and quantum value of the CHSH game.
import numpy as np
from toqito.nonlocal_games.xor_game import XORGame
# The probability matrix.
prob_mat = np.array([[1/4, 1/4], [1/4, 1/4]])
# The predicate matrix.
pred_mat = np.array([[0, 0], [0, 1]])
# Define CHSH game from matrices.
chsh = XORGame(prob_mat, pred_mat)
chsh.classical_value()
# 0.75
chsh.quantum_value()
# 0.8535533
```
**Detailed documentation on all available methods, options, and input formats is available at [ReadTheDocs](https://toqito.readthedocs.io/en/latest/).**
