  The charge and exchange statistics of an elementary excitation manifest in
quantum coherent oscillations that can be explored in interferometry
measurements. Quantum Hall interferometers are primary tools to uncover
unconventional quantum statistics associated with fractional and non-Abelian
anyons of a two-dimensional system, the latter being the foundation of
topological quantum computing. Graphene interferometers offer new avenues to
explore the physics of exotic excitations due to their relatively small
charging energies and sharp confinement potentials. Bilayer graphene possesses
a true band gap to facilitate the formation of quantum confinement and exhibits
the most robust even-denominator fractional quantum Hall states that may host
non-Abelian anyons. Here we present the design and fabrication of a split-gated
bilayer graphene Fabry-P\'erot interferometer and experimental evidence of
Aharonov-Bohm interference at multiple integer quantum Hall states. The
versatility of the device allows us to study a wide range of scenarios,
determine the velocities of edge states, and assess dephasing mechanisms of the
interferometer. These results pave the way to the quest of non-Abelian
statistics in this promising device platform.
