Quantum interferometers are powerful tools for probing the wave-nature andexchange statistics of indistinguishable particles. Of particular interest areinterferometers formed by the chiral, one-dimensional (1D) edge channels of thequantum Hall effect (QHE) that guide electrons without dissipation. Usingquantum point contacts (QPCs) as beamsplitters, these 1D channels can be splitand recombined, enabling interference of charged particles. Such quantum Hallinterferometers (QHIs) can be used for studying exchange statistics of anyonicquasiparticles. In this study we develop a robust QHI fabrication technique invan der Waals (vdW) materials and realize a graphene-based Fabry-P\'erot (FP)QHI. By careful heterostructure design, we are able to measure pureAharonov-Bohm (AB) interference effect in the integer QHE, a major technicalchallenge in finite size FP interferometers. We find that integer edge modesexhibit high visibility interference due to relatively large velocities andlong phase coherence lengths. Our QHI with tunable QPCs presents a versatileplatform for interferometer studies in vdW materials and enables futureexperiments in the fractional QHE.
