Q3 is a Mathematica(R) application written in the Wolfram Language. Q3 is to help study quantum information systems, quantum many-body systems, and quantum spin systems; hence the name Q3. It provides various tools and utilities for symbolic and numerical calculations in these areas of quantum physics.

Q3 requires Mathematica v12.2 or later.

Q3 provides a fully automatic installation and update. Please take a look at the Installation Guide for the instructions.

Once Q3 is installed, put Q3 or Q3/guide/Q3 in the search field of the Wolfram Language Documentation Center (Mathematica Help window) to get users' guides and tutorials on Q3; see the following screenshots.

For more advanced uses of Q3, take a look at textbook "A Quantum Computation Workbook" (Springer, March 2022). A compilation of the Mathematica(R) Notebook files that have been used to generate the demonstrations in this textbook is available from the QuantumWorkbook repository.

If this is your first time to use Mathematica, this guide written by Stephen Wolfram himself might be a good starting point: An Elementary Introduction to the Wolfram Language (2nd edition).
