**Condensed Matter Theory Group Seminar****Full Counting Statistics of Photons Emitted by Double Quantum Dot****Time:**4:30 pm**Place:**Chamberin 5310**Speaker:**Canran Xu, Physics Department**Abstract:**We analyze the full counting statistics of photons emitted by a double quantum dot (DQD) coupled to a high-quality microwave resonator by electric dipole interaction. We show that at the resonant condition between the energy splitting of the DQD and the photon energy in the resonator, photon statistics exhibits both a sub-Poissonian distribution and antibunching. In the ideal case, when the system decoherence stems only from photodetection, the photon noise is reduced below one-half of the noise for the Poisson distribution and is consistent 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.**Host:**Natalia Perkins- Add this event to your calendar
