The LEAP algorithm improves scaling across these dimensions using iterative circuit synthesis, incremental re-optimization, dimensionality reduction, and improved numerical optimization. LEAP draws on the design of the optimal synthesis algorithm QSearch by extending it with an incremental approach to determine constant prefix solutions for a ","authors_text":"Costin Iancu, Ed Younis, Ethan Smith, Jeffrey Larson, Marc G.
