Hanbury Brown–Twiss Correlations to Probe the Population Statistics of GHz Photons Emitted by Conductors
Hanbury Brown–Twiss Correlations to Probe the Population Statistics of GHz Photons Emitted by Conductors
We present the first study of the statistics of GHz photons in quantum circuits, using Hanbury Brown and Twiss correlations. The super-Poissonian and Poissonian photon statistics of thermal and coherent sources, respectively, made of a resistor and a radio frequency generator, are measured down to the quantum regime at milli-Kelvin …
