### What is your issue?
Hi,
I wanted to construct a QAOA circuit for Traveling Salesman Problem using QUIMBs built-in function circ_qaoa. But the function does not contain the external magnetic fie…

Dear Jose,
I would like to report an inconsistency between results obtained for the ground-state energy of a four-site cluster Hubbard chain using dmrgpy and Itensor.jl. The Hubbard model includes …

Hello,
we are working on an extended Hilbert space in order to calculate the ground state energy of the Bose-Hubbard model. We added spin 1/2 sites between every boson site in the one-dimensional ch…

Hello, `quilc` wizards! I've caused an interesting crash on ARM64.
In order to get `quilc` to compile on ARM64, I had to [hack on `cffi` a little bit](https://github.com/cffi/cffi/issues/334), so p…

When debugging `tests/li_solv` I noticed that no information about the `Environment` is printed to the stdout output file, so it is impossible to deduce that the calculation is performed in an implici…
