There was a problem hiding this comment.
Look good, thank you.
Very clean representation of states.
I would go with basis_expansion.

Description
Added
Qobj.print_basis_expansion()which returns string representations for states of the form "(0.24+0.3j) |0010> + ...", i.e. essentially the inverse ofqutip.ket()/qutip.bra().This works for any dimensions, i.e.
qutip.basis([5, 5, 5], [4, 0, 2]).print_basis_expansion()would return"(1+0j) |4, 0, 2>".I'd be happy for suggestions for a better name for this function, since it doesn't actually print anything to console, but I found this name less unwieldy than e.g.
.basis_expansion_string()and clearer than just.basis_expansion().Related issues or PRs
