An important tool for studying sources of both classical and quantum radiation is the temporal correlation functions. In the optical range, single-photon detectors are used for their measurement. In the microwave range, such efficient detectors do not yet exist. However, with detectors that measure the linear characteristics of the electromagnetic field, such as voltage, it is also possible to measure correlation functions. In this work, we demonstrate the phenomenon of antibunching using second-order correlation functions, measured by the technique we developed, for the radiation of an artificial superconducting atom, naturally divided in a one-dimensional coplanar waveguide.
