However, its detection with microwave circuits is challenging. Here, we propose to use the photon-assisted shot noise for on-chip radiation detection. It is based on the low-frequency current noise generated by the partitioning of photon-excited electrons and holes, which are scattered inside the conductor. For a given electromagnetic coupling to the radiation, the photon-assisted shot noise response is shown to be independent on the nature and geometry of the quantum conductor used for the detection, up to a Fano factor, characterizing the type of scattering mechanism. Ordered in temperature or frequency range, from few tens of mK or GHz to several hundred of K or THz respectively, a wide variety of conductors can be used like Quantum Point Contacts (this work), diffusive metallic or semi-conducting films, graphene, carbon nanotubes and even molecule, opening new experimental opportunities in quantum physics. %G English %2 https://cea.hal.science/cea-01366527/document %2 https://cea.hal.science/cea-01366527/file/ncomms7130.pdf %L cea-01366527 %U https://cea.hal.science/cea-01366527 %~ CEA %~ CNRS %~ OPENAIRE %~ IRAMIS-SPEC %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ IRAMIS %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE
