Figure 3: Coherent control with few-photon pulses.
From: Coherent manipulation of a solid-state artificial atom with few photons
(a) H-polarized emission intensity as a function of the excitation power (top axis) and the average photon number 〈n〉 (bottom axis) for two pulse durations (12 and 56 ps). (b) Calculated H-polarized emission as a function of 〈n〉 for two pulse durations. (c) Calculated probability to find the QD in its excited state after the pulse as a function of 〈n〉 for 12 and 56 ps pulses. (d) Calculated probability to find the QD in the exciton state as a function of time for a 56 ps excitation pulse (dashed line). Black: case of a coherent pulse with 〈n〉=1. Red: case of a single photon Fock state. (e) Mean photon number 〈n〉 needed to induce a π-pulse as a function of the pulse duration for various values of ΔFSS.
