The measurement of the electron number probes the QD loading dynamics even in the limit of slow gate voltage rise-times, when the pumped current is too small to measure. Using simulations we show that, with optimised QD-PC coupling, the experiment can make single-shot measurements of the number of electrons in the QD with sufficiently high fidelity to test the error rate of the elect","authors_text":"G.A.C.Jones, I.Farrer, J.D.Fletcher, J.P.Griffiths, M.Kataoka, P.See, S.P.Giblin, T.J.B.M.
