  One remarkable feature of strongly correlated systems is the phenomenon of
fractionalization where quasiparticles carry only a fraction of the charge or
spin of the elementary constituents. Such quasiparticles often present anyonic
statistics in two dimensions and lie at the heart of the fractional quantum
Hall effect. We discuss the observation of fractionalization and anyonic
statistics already in the integer quantum Hall effect coupled to a metallic
island. A continuous fractional emitter is proposed, which sends dilute beams
of non-integer charges, and its full counting statistics is obtained. The
fractional charge is governed solely by the number of ballistic channels
covered by the island and it is one half of the electron charge for a single
ballistic channel. We further characterize the mixing of two such fractional
beams through a quantum point contact beam splitter. We predict negative
cross-correlations, in strong contrast with free electrons, that depend on the
double exchange phase between electrons and the fractional charges emulating
anyons. The result is similar to a genuine fractional edge state as recently
measured at filling $\nu = 1/3$. We revisit the physical interpretation of this
experiment and point towards a direct braiding measurement rather than a
deviation from fermionic antibunching.
