Summary form only given. We precisely control the quantum states of more than 1000 strontium atoms to achieve a more stable and accurate atomic clock than any existing atomic clocks, with both stability and uncertainty reaching the 10-18level. Such advanced clocks will allow us to test fundamental laws of nature and fuel applications in a wide range of technological frontiers.

In this brief contribution I will highlight some directions where the developments in the frontier of (quantum) metrology may be key for fundamental high energy physics (HEP). I will focus on the detection of dark matter and gravitational waves, and introduce ideas from atomic clocks and magnetometers, large atomic interferometers and detection of small fields in electromagnetic cavities. Far from being comprehensive, this contribution is an invitation to everyone in the HEP and quantum technologies communities to explore this fascinating topic.
