Rotation of the average output polarisation in the Poincaré sphere as a function of the detuning (see colorscale) between the laser and the |↑⟩ -|↑↓⇑⟩ transition, for the three different magnetic fields. The bottom-right panel displays the output polarisation in a top view of the Poincaré sphere for the three magnetic fields (see also Supplementary Movies 1 – 3 for complete 3D visualisations). The red arrows describe increasing laser-QD detunings.
