Quantum Package is an open-source programming environment for quantum chemistry, which was built for developpers in order to help the design of new computational methods, especially in the field of wave function theory.

From the user point of view, Quantum Package proposes a stand-alone path to use optimized selected configuration interaction methods based on the CIPSI algorithm that can efficiently approcah full CI quality for relatively large systems.
