In analogy with quantum optics, short-time correlations of the current fluctuations are
measured and used to assess the quality of the single-particle emission of a recently
introduced on-demand electron source. We observe, in the context of electronics, the
fundamental noise limit associated with the quantum fluctuations of the emission time of
single particles, or quantum jittering. In optimum operating conditions of the source, the
noise reduces to the quantum jitter limit, which demonstrates single-particle emission …
