The naturalness of the QCD axion comes from the strong CP problem, making it one of the most well-motivated dark matter candidates. Especially, with the development of quantum sensors, Axion Dark Matter eXperiment (ADMX) can reach to the golden parameter space of QCD axion dark matter for both benchmark models: Kim–Shifman–Vainshtein–Zakharov (KSVZ) and Dine–Fischler–Srednicki–Zhitnitsky (DFSZ). In this talk, I will give an overview on the current status of the ADMX main experiment and near future plans.
