TL;DR Summary
The ground state obtained by ED is not in a suitable representation and I am looking for a way to define spin operators working with that.
Hi,
I want to measure spin components of a ground state of some models. These ground states are obtained by ED. The states for constructing the Hamiltonian are integers representing spins in binary. As the ground state (and the other eigenvectors) are now not anymore in a suitable representation (just vectors with doubles as components instead of integers), I am looking for a way to define my spin operators to measure the components suitable for my code.

I tried rewriting as Correlation function or with the partition sum. Do you have any ideas?
