A large amount of pedagogical information on QuTiP is available at this URL: https://qutip.org/

2022:	A very brief overview of QuTiP is available here (~6 minutes) [MP4]. A very short poster with an overview of QuTiP is available here [Poster]. The presentation and the poster were prepared by Simon Cross, a member of our group.
2025:	More than 3.5 Million downloads! Our software QuTiP (Quantum Toolbox in Python) is used by very many research groups and companies around the world. The PyPi (see graph) and Anaconda installs combined are more than 3.5 million to date.
