Dots are the experimentally measured data, and the lines with corresponding colors without shaded areas represent steering bounds calculated for each point, taking into account the number of measurement settings and measured heralding efficiency. Lines with shaded areas correspond to the dynamic steering scenario when θ was adjusted during the measurement, see main text for details. The dashed black line is the theoretical prediction for steering with polarization qubits. Error bars and shaded regions correspond to a measurement uncertainty equal to two standard deviations total.
