a QPC conductance data versus gate voltage VG at field B = 11.3 Tesla (ν = 2/5). A plateau at conductance \(\frac{{e}^{2}}{3h}\) signals the reflection of the first inner 2/5 edge channel and the formation of a 1/3 fractional state in the QPC. The red and blue filled circles, labeled A and B, indicate the working points used for probing the coherence of respectively e/3 and e/5 anyons. b DC cross-correlated noise ((\(- {S}_{{I}_{3}{I}_{4}}\)) data (blue circles), measured at working point A, and comparison with Eq. (7) for constant transmission D = 0.984, temperature 15 mK and e* = e/3 (red dashed curve). The statistical measurement noise errors are \(\pm\)0.8 × 10−30A2/Hz for the typical 15 s measurement time. c Shot noise data (black and blue filled circles) versus time delay measured at working point A for a 14.15 GHz microwave excitation and two RF source powers differing by 3 dB. The red dashed lines are comparisons with Eq. (6) using \({e}^{*}=\frac{e}{3}\) including a small 10−29 A2/Hz noise offset. The statistical measurement noise errors are \(\pm\)2 × 10−30 A2/Hz for the 3 s measurement time per time delay point used.
