This Article contains errors in the labelling of the ticks of the x axis in Fig. 5. In panel a, the x axis values should have been labelled ‘−10 ns’ and ‘10 ns’ rather than ‘−5 ns’ and ‘5 ns’. In panels b and c, the x axis values should have been labelled ‘−25 ns’ and ‘25 ns’ rather than ‘−10 ns’ and ‘10 ns’. The correct version of this figure appears below.

Figure 5 | Polarization correlation results from the ST-ELED under electrically pulsed injection at repetition rate of 400 MHz. (a) Normalized correlation functions for co- and cross-polarized XX and X photons in HV, DA and RL bases. (b,c) Degree of correlation C in given basis, in which correlation in HV and DA bases (C>0) and anti-correlation (C<0) in RL basis are obtained without temporal gate (Δτ=2.5 ns) and with a temporal gate width Δτ=0.8 ns centred at 0 delay time, respectively.
