where N m is the repetition number of measurements for obtaining mth observable expecta- ). There are also some efforts to reduce N T at the level of algorithm such as ADAPT using Valdemoro's reconstruction (ADAPT-V/Vx) Ansätze. However, because of the operator order problem, ADAPT-V/Vx can hardly reach comparable accuracy with the same level of circuit depth compared to the original ADAPT-VQE.
