QSym² (pronounced q-sym-squared) has been developed and maintained by Dr Bang C. Huynh at the University of Nottingham, UK since July 2022 with scientific support from Prof. Andrew M. Wibowo-Teale and Dr Meilani Wibowo-Teale and financial support from the ERC grant under the topDFT project.

The logo for QSym², which is a stylised stellated octahedron, was designed with artistic support from Mr Thinh Nguyen.
