## Description

- description: Graphene quantum dots are promising candidates for qubits due to weak
    spin-orbit interaction and minimal hyperfine interactions. The hyperfine interaction,
    controllable via isotopic purification, could be the key to further improving
    the coherence. Isotopically enriched graphene has been made by chemical vapor
    deposition. Here we use isotopically enriched graphite crystals both 12C and 13C
    grown by high-pressure-high-temperature synthesis to exfoliate graphene layers.
    We fabricated Hall bar devices and performed quantum transport measurements, revealing
    mobilities exceeding 10^5cm2/V s and a long mean free path of microns. Shubnikov-de
    Haas oscillations, quantum Hall effect up to the filling factor of one, and Brown-Zak
    oscillations due to the alignment of hBN and graphene are observed thanks to the
    high mobility. These results constitute a material platform for physics and engineering
    of isotopically-enriched graphene qubits.
