I am beginner to open quantum system I used qutip to help me Not just for numerical calculations But code itself is readable This is my way to learn the topic About piqs Congratulations for u implementation I fellow code step by step But I can't pass spin algebra I can't understand permute function ,what it do It is complicated no reference or tutorial I wish to give us a tutorial about it Best regards

Dear @gharib85,

Thank you for positive comments on PIQS (cc @sahmed95).

We give extensive explanations on the permutational invariance of the system and dynamics in the accompanying paper, https://arxiv.org/abs/1805.05129, see especially Sec. II, where additional useful references are provided. Further analytical understanding can be gained in the Appendix of that manuscript.

Several tutorials are already hosted at https://github.com/nathanshammah/notebooks/tree/master/piqs_notebooks and at http://qutip.org/tutorials.html under the "Permutational invariant Lindblad dynamics" section.

Best wishes,

Nathan
