We report new experimental results on the search for dark photons based on a near -quantum -limited haloscope equipped with a superconducting cavity. The loaded quality factor of the superconducting cavity is 6 x 10 5 , so that the expected signal from dark -photon dark matter can be enhanced by more than one order compared to a copper cavity. A Josephson parametric amplifier with a near -quantum -limited noise temperature has been utilized to minimize the noise during the search. Furthermore, a digital acquisition card based on field programmable gate arrays has been utilized to maximize data collection efficiency with a duty cycle being 100%. This work has established the most stringent constraints on dark photons at around 26 .965 mu eV. In the future, our apparatus can be extended to search for other dark matter candidates, such as axions and axionlike particles, and scrutinize new physics beyond the Standard Model.
