Figure 2

(a) Two-photon correlation count and (b) photoluminescence (PL) count rate (black line), summed over all detectors, and quantum correlation (red dots), summed over all detector pairs, for a single quantum dot (QD). Error bars represent ±σ statistical error (grey). (c) A single QD imaged by the bundle camera using N=1,500 photons acquired in 15 ms. Colour bar represent PL count. Scale bar, 100 μm. (d) Two-dimensional localization error σxy measured for a single QD (solid blue) and theoretical precision (see text). Inset shows 200 localizations using N=1,500 photons for a single QD, where the localization precision is σxy=20 nm. Scale bar, 100 μm.
