a Measured left/right source QPC dc transmission as a function of bias voltage, shown in light/dark blue, respectively. b Sum of sources' shot noise SΣ vs source bias voltage Vs. The orange lines display Eq. (3) with T = 11 mK, the independently measured temperature. c Measured excess shot noise S12/(τc(1 − τc)) as a function of source shot noise SΣ for a small source QPC transmission τs = 0.05/0.95 (full/empty dots respectively). The purple lines display the strong inter-channel coupling prediction for δt = 64 ps. The green lines denotes the slope, i.e., the Fano factor (see Main text), yielding P ≃ −0.38/−0.56 for τs = 0.05/0.95 respectively. In all panels full/open circles and solid/dashed lines denote τs = 0.05/0.95, respectively.
