Research Type Theoretical In this paper, we conduct a systematic study for quantum algorithms and lower bounds for minimizing the maximum of N convex, Lipschitz functions. On one hand, we develop quantum algorithms with an improved complexity bound of O(Nϵ 5/3 + ϵ 8/3).1 On the other hand, we prove that quantum algorithms must take Ω(Nϵ 2/3) queries to a first order quantum oracle, showing that our dependence on N is optimal up to poly-logarithmic factors.
