Two-particle sub-wavelength Quantum Correlation Microscopy
arXiv:1810.01712 · doi:10.1103/PhysRevA.101.013810
Abstract
Typically, optical microscopy uses the wavelike properties of light to image a scene. However, photon arrival times provide more information about emitter properties than the classical intensity alone. Here, we show that the Hanbury Brown and Twiss experiment (second-order correlation function) measures the intensity asymmetry of two single photon emitters, and that by combining the total number of detected photons with the zero-lag value of the correlation function, the positions and relative brightness of two emitters in two dimensions can be resolved from only three measurement positions -- trilateration, a result that is impossible to achieve on the basis of intensity measurements alone.
