cd Qualtran/
pip install -e .

You can also install the latest tagged release using pip:

pip install qualtran

You can also install the latest state of the main branch:

pip install git+https://github.com/quantumlib/Qualtran

Qualtran provides a GUI for estimating the physical resources (qubits, magic states, runtime, ..etc) needed to run a quantum algorithm. The GUI can be run locally by running:

cd $QUALTRAN_HOME
python -m qualtran.surface_code.ui
