Realtime photon‐number resolution & Imaging via photon counting
17:50 - 18:10
Andrew White We introduce a hardware processor capable of analysing the continuous output signal from transition edge-sensors (TES's), giving us near-real information about photon number. We discriminate up to 15 photons, with certainties ranging from 99.9999996% for 2 photons, to 98.0% for 13 photons. We implement a general imaging method by measuring the complex degree of coherence using linear optics and our photon-number-resolving detectors. Testing our method on by measuring the size and position of a small distant source of pseudo-thermal light, we find it outperforms the traditional imaging method by an order of magnitude in precision.
