a, Transmission of the FPI as a function of B and \({V}_{\rm{G}}^{{{\rm{d.c.}}}}\), showing a periodic behaviour. The two insets show cuts along the dotted lines drawn on the central plot as a function of the field (blue) and d.c. gate voltage (red). b, Temperature dependence of the contrast of FPI oscillations. c, Evolution of the normalized contrast of oscillations CN as a function of the width τe of single-electron Lorentzian pulses. The data points are extracted from a sinusoidal fit of the oscillations of \(T({V}\,_{\rm{G}}^{{{\rm{d.c.}}}})\) and the error bars are obtained from the resulting covariance matrix. The dashed line represents the overlap of two Lorentzian wavefunctions CN(τL/τe) as a function of τe, with τL = 30 ps.
