In general, you may use the code from Qiskit Pocket Guide in your programs and documentation. You do not need to contact the authors for permission unless you're reproducing a significant portion of the code. For example, writing a program that uses several chunks of code from this book does not require permission. Answering a question by citing this book and quoting example code does not require permission. On the other hand, selling or distributing a CD-ROM of examples from Qiskit Pocket Guide does require permission. Incorporating a significant amount of example code from this book into your product's documentation does require permission.

We appreciate, but do not require, attribution. An attribution usually includes the title, author, publisher, and ISBN.

If you think your use of code examples falls outside fair use or the permission given here, feel free to contact O'Reilly at [email protected].

Please note that the examples are not production code and have not been carefully tested. They are provided "as-is" and come with no warranty of any kind.

You need a way to run Python and Jupyter Notebooks:

pip install jupyter

This is tested on Qiskit Terra 0.20. This and other dependencies can be installed via Pip:

pip install -r requirements.txt 

wget http://github.com/qiskit-community/qiskit-pocket-guide/archive/refs/heads/main.zip 
unzip main.zip
