A deterministic algorithm prepares arbitrary multi-qudit states in a definite-weight subspace via Gray-code ordering of multiset permutations, reducing preparation to controlled 2-qudit Gray rotations, and is demonstrated on Bethe states of the SU(3) Heisenberg model and SU(d) Dicke states.
The Effective Bethe Ansatz approximates ground and first excited states of the spin-1 bilinear-biquadratic chain in finite windows around both integrable endpoints, with fidelity to exact diagonalization degrading controllably and entanglement entropy reproduced poorly.
