Hi @dfelmanl , I would say the answer is still the same as in this post: > [@Non-Abelian Quantum Number](https://itensor.discourse.group/t/non-abelian-quantum-number/1905/2): > > Hi cfengno1, The non-abelian implementation for iTensor is a work in progress. I hope to have a functional version by the end of the year 2024, however the first release needs to be synchronized with many other features under development inside NDTensors. The new system is coming along well, and the core features like tensor addition and contraction are essentially working. But the system is currently not plugged into ITensor yet, and also still needs much testing and refactoring and such. So I would realistically expect it will be some months away. --- _[View the full topic](https://itensor.discourse.group/t/su-2-implementation/2127)._
