Efficient Eigenstate Preparation in an Integrable Model with Hilbert Space Fragmentation
We demonstrate that eigenstates of selected interacting spin chains can be efficiently prepared using quantum circuits with polynomial depth in system size and particle number. While this is well established for free-fermionic spin chains, we extend this result to the folded XXZ model, an integrable...
