Abstract: 

 

In this talk, I will present our efforts to use quantum technologies in order to probe cosmological signals. I will first present how quantum sensing techniques can be used to probe axion dark matter. In particular, I will present our ongoing experiments with a phase resolved quantum enhanced haloscope, which holds promise to speed up substantially axion dark matter search. I will then show how one can extend these ideas to radioastronomical signals. I will show first proof of principle experiments on 21-cm signals. The extension to the problem of detecting 21-cm signals of the Cosmic Dawn or the Epoch of Reionization in the early Universe will be discussed.
