## Description

- description: We show that electron-hole mixing is drastically reduced in high mobility
    graphene van-der-Waals heterostructures thanks to the full degeneracy lifting
    of the Landau levels, enabling quantum point contact operation with full channel
    pinch-off. We demonstrate gate-tunable selective transmission of integer and fractional
    quantum Hall edge channels through the quantum point contact. This gate-control
    of edge channels opens the door to quantum Hall interferometry and electron quantum
    optics experiments in the integer and fractional quantum Hall regimes of graphene.
