Optimal single electron sources emit regular streams of particles,
displaying no low frequency charge current noise. Due to the wavepacket
nature of the emitted particles, the energy is however fluctuating, giving
rise to heat current noise. We investigate theoretically [1] this quantum
source of heat noise for an emitter coupled to an electronic probe in the
hot-electron regime. The distribution of temperature and potential
fluctuations induced in the probe is shown to provide direct information
on the single particle wavefunction properties and display strong
non-classical features
