## Description

- description: 'We show ballistic transport and quantized conductance of size-confined
    Dirac fermions in lithographically-defined graphene quantum point contacts. At
    high charge carrier densities, the observed conductance agrees excellently with
    the Landauer theory of ballistic transport, without any adjustable parameter.
    Experimental data and simulations for the evolution of the conductance with magnetic
    field unambiguously confirm the identification of size quantization in the constriction. '
