Inspired by a recent classical distribution-free junta tester by Chen, Liu, Serverdio, Sheng, and Xie (STOC'18), we construct a quantum tester for the same problem with complexity O(k/ε), which constitutes a quadratic improvement.We also prove that there is no efficient quantum algorithm for this problem using quantum examples as opposed to quantum membership queries.This result was obtained independently from the O(k/ε) algorithm for this problem by
