Thet test started failing for Windows because of precision issues. I didn't dig very deep on whether it's something related to the new release or whether the test was flaky in the first place (probably more likely) so I just increased the precision and it seems to work fine.

The relevant statements in the cell below, that depend on the precision, are:

    "inds, = np.where(abs(result.final_state_vector) > 1e-8)\n",
    "assert len(inds) == 1\n",

" print(inp, '->', result.dirac_notation())\n",
" assert result.dirac_notation()[1:-1] == \"\".join(str(x) for x in out)"
]
