The bethe ansatz as a quantum circuit

HIGHLIGHTS

• What: Progress in this direction was made, where an algorithm to prepare eigenstates of the XXZ model was introduced. Throughout the paper the authors focus on a spin-1/2 chain. Published under CC-BY 4.0. input Hr,k+1 Hr,M output Hr-i,k Hr-i,M dimensions dr-i,k × dr,k+1 dr-i,M × dr,M 4 Ansatz for the ABC gates Below the authors propose analytical expressions for the (i,r) maps Pk building the ABC gates with arbitrary M and N. The authors focus first on the leftmost qubit . . .
