Currently, the `rydberg_feature_map` [here](https://github.com/pasqal-io/qadence-libs/blob/b3248d476ac6b1a640910fd1699288465b34db63/qadence_libs/constructors/rydberg_feature_maps.py#L20) does not pass…

### Background
Nowadays, people can directly obtain the Hamiltonian of a system by machine learning, thus bypassing the time-consuming self-consistent process, such as **DeepH**.
However, there i…

We are implementing FanPT. The basic idea is in the [recent paper](https://pubs.acs.org/doi/full/10.1021/acs.jpca.4c00855).
Recall that the FanCI equations are
$$
\braket{\mathbf{m}|\hat{H}|\Ps…

Dear Zhong Yang
When I tried to run HamGNN in the GPU platform, I encountered some problem due to the version of the python library. However, the library that I have installed is completely in accord…

**Describe the bug**
The several results in the tutorial are not correctly drawn because of KeyboardInterrupt.
I found there are two KeyboardInterrupt at

I expected Hamiltonians to be invariant under changing the order in which parallel edges are added, but this appears not to be the case.
Is this a change in coordinates somehow, or a bug?

Dear developer,
I am calculating the z2 invariant of a 2D system with tight binding Hamiltonian. The Hamiltonian is complex conjugate and time reversal invariant. When I calculate z2 invariant it g…

Hi all,
I am working on a new algorithm that is to be implementable in an actual experiment. In order to get the feeling about what is going on, I would need to compute the expectation value for a…
