Quantum Submodular Maximization

Yonggang Jiang, Xiaoming Sun, Penghui Yao +3

We study the quantum query complexity of maximizing a non-negative submodular function, considering both the unconstrained setting and, for monotone functions, a cardinality constr…

Optimal Quantum Junta Testing without Inverse Queries

Jinge Bao, Minbo Gao, Penghui Yao

We study the query complexity of testing quantum juntas. Given an unknown -qubit unitary or quantum channel, the goal is to decide whether it acts nontrivially on at most qu…
