{"abstract":[{"text":"At optical frequencies the radiation produced by a source, such as a laser, a black body or a single-photon emitter, is frequently characterized by analysing the temporal correlations of emitted photons using single-photon counters. At microwave frequencies, however, there are no efficient single-photon counters yet. Instead, well-developed linear amplifiers allow for efficient measurement of the amplitude of an electromagnetic field. Here, we demonstrate first- and second-order correlation function measurements of a pulsed microwave-frequency single-photon source integrated on the same chip with a 50/50 beam splitter followed by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon coherence in first-order and photon antibunching in second-order correlation function measurements of the propagating fields.","lang":"eng"}],"publisher":"Nature Publishing Group","author":[{"first_name":"Deniz","last_name":"Bozyigit","full_name":"Bozyigit, Deniz"},{"first_name":"C","last_name":"Lang","full_name":"Lang, C"},{"last_name":"Steffen","first_name":"L.","full_name":"Steffen, L.
