SUMMARY:Full Counting Statistics of Photons Emitted by Double Quantum 
 Dot\, Condensed Matter Theory Group Seminar\, Canran Xu\, Physics Depa
 rtment
DESCRIPTION:We analyze the full counting statistics of photons emitted
  by a double quantum dot (DQD) coupled to a high-quality microwave res
 onator by electric dipole interaction. We show that at the resonant co
 ndition between the energy splitting of the DQD and the photon energy 
 in the resonator\, photon statistics exhibits both a sub-Poissonian di
 stribution and antibunching. In the ideal case\, when the system decoh
 erence stems only from photodetection\, the photon noise is reduced be
 low one-half of the noise for the Poisson distribution and is consiste
 nt with current noise. The photon distribution remains sub-Poissonian 
 even at moderate decoherence in the DQD. We demonstrate that Josephson
  junction based photomultipliers can be used to experimentally assess 
 statistics of emitted photons.
