WebMay 1, 2006 · Geodesic analysis thus offers a potentially powerful approacb to theproblem of proving quantum circuit lower bounds. In this paper we construct severalFinsler metrics whose minimal length geodesics provide lower bounds on quantum circuitsize. For eacb Finsler metric we give a procedure to compute the corresponding geodesicequation. Web2. Circuit Lower Bounds from #SAT Algorithms: Williams’ paradigm [Wil13,Wil14, MW18] for lower bounds gives circuit lower bounds from circuit satisfiability algorithms. We build upon this paradigm and study lower bounds that can be obtained from algorithms which count the number of satisfying solutions for a circuit i.e. #SAT algorithms. Infor-
