sentences:  In addition to the excitation of the quantum dot that was achieved, they were also able to collect the photon that was emitted with a micro-PL setup.This allows for resonant coherent control of the ground state of the quantum dot while also collecting the photons emitted from the fluorescence.In 2007, G. Wrigge, I. Gerhardt, J. Hwang, G. Zumofen, and V. Sandoghdar Developed and efficient method to observe resonance fluorescence for an entire molecule as opposed to its typical observation in a single atom.
