SPRINT and GRADE cut Toffoli cost 4.5x versus prior Trotter methods for Li4Mn2O X-ray spectrum simulation while using 5.5x fewer qubits than qubitization alternatives.
This algebraic constraint reduces the number of independent error terms in the Baker–Campbell–Hausdorff expansion of any product formula built frome −iαT ande −iβV
