I am going to start development of an all-atom Structure-based model Hamiltonian on the `devel` branch. This shouldn't interfere with other branches but we should be conscious to merge branches whenev…

When the code is available to treat the padded Hamiltonian matrix, we should set the good value for block_size_r (and block_size_c).
First,
1. Manually Given or Default Setting:

The appearance of graphs drawn with the GraphViz tools (e.g., dot) depends on the order in which nodes are defined in the dot file created by the as_DOT() functions of Graph and Digraph. To achieve re…

Sometimes we need to deal with time-dependent Hamiltonian(eg. the effective Hamiltonian in Hierarchy of Matrix Product States). I have tried two methods, but each of them has some drawbacks.
1. Devid…

Hi, I want to print Hamiltonian, but I don't know where to add a "print" during the calculation.

Since [Hamiltonians are now observables with differentiable coefficients](https://github.com/PennyLaneAI/pennylane/pull/1483), drawing a circuit with a Hamiltonian looks as follows:
```python
coef…

### What should we add?
I didn't find any built-in Hamiltonian simulation protocol in qiskit. So I'm thinking of building one according to the paper--Simulation Hamiltonian dynamics with a truncate…

Focus on for 3 component system.
Add new energy calculations based on ECI

## Sum
`Sum` should be handled the same way as `Hamiltonian` and `LinearCombination`, which was partially addressed in https://github.com/amazon-braket/amazon-braket-pennylane-plugin-python/pull/25…

See https://discourse.julialang.org/t/quantumoptics-jl-time-dependent-hamiltonian-cannot-run/113448/9?u=krastanov
When we have `H(t,rho) -> matrix`, an assert fails in `master_dynamic`. We can have…
