In our experiment, we select a six-wave mixing path specifically designed to minimize the generation of optical noise. This allows us to perform coherent upconversion of 13.9 GHz signal to near-infrared photons, and subsequently use a photon-counting detector. The intrinsic noise in the process corresponds to only 3.8 K equivalent noise temperature. With this device, capable of effectively counting the microwave photons, we are able to observe upconverted thermal radiation, and thus observe its second-order correlation function, as well as two-photon interference between thermal radiation and coherent signal. As additional benefits, the system has a large and tunable bandwidth, and an excellent dynamic range of almost 60 dB. The intrinsic efficiency of the device reaches 1%, and could be further improved by employing cavities, also potentially leading to strong-coupling effects at room temperature. We envisage that the presented method could be both employed as a very sensitive microwave detector in many applications, even including space-borne detectors, as well as ported to cryogenic systems and used deeply in the quantum regime.
