PennyLane is an open-source quantum software platform for quantum (github.com)

For those interested in compilers/LLVM/MLIR, the underlying compiler (Catalyst) may also be interesting: https://github.com/pennylaneai/catalyst

...computing, quantum machine learning, and quantum chemistry (probably a title length limit)

No, Penny Lane is in my ears and in my eyes....

Interesting to see it mention quantum chemistry, could anyone familiar with the field chimu in on whether it is viable to get accurate bond energies? It mentions Hartree-Fock, but I thought that that wasn't accurate enough to find transition states.
