hi all,
I am trying to compute the expectation value of some Fermi Hubbard hamiltonian where the terms are of this kind
```
1.0 [] +
-0.5 [X0 Z1 X2] +
-0.5 [X0 Z1 Z2 Z3 X4] +
-0.5 [Y0 Z1 Y2] …

This comes from an example simulating the Fermi-Hubbard model where the time-evolved wavefunction is incorrect.
```python
import numpy as np
from scipy.linalg import expm
import openfermion as…
