  We measure telegraph noise of current fluctuations in an electrostatically
defined quantum dot in bilayer graphene by real-time detection of single
electron tunneling with a capacitively coupled neighboring quantum dot.
Suppression of the second and third cumulant (related to shot noise) in a
tunable graphene quantum dot is demonstrated experimentally. With this method
we demonstrate the ability to measure very low current and noise levels.
Furthermore, we use this method to investigate the first spin excited state, an
essential prerequisite to measure spin relaxation.
