Query: Statistics of radiation at Josephson parametric resonance   Motivated by recent experiments, we study theoretically the full counting
statistics of radiation emitted below the threshold of parametric resonance in
a Josephson junction circuit. In contrast to most optical systems, a
significant part of emitted radiation can be collected and converted to an
output signal. This permits studying the correlations of the radiation.
  To quantify the correlations, we derive a closed expression for full counting
statistics in the limit of long measurement times. We demonstrate that the
statistics can be interpreted in terms of uncorrelated bursts each encompassing
2N photons, this accounts for the bunching of the photon pairs produced in
course of the parametric resonance. We present the details of the burst rates.
In addition, we study the time correlations within the bursts and discuss
experimental signatures of the statistics deriving the frequency-resolved
cross-correlations.
