      abstract     = {Ultralight mechanical resonators based on low-dimensional
                      materials are well suited as exceptional transducers of
                      minuscule forces or mass changes. However, the low
                      dimensionality also provides a challenge to minimize
                      resistive losses and heating. Here, we report on a novel
                      approach that aims to combine different two-dimensional (2D)
                      materials to tackle this challenge. We fabricated a
                      heterostructure mechanical resonator consisting of few
                      layers of niobium diselenide (NbSe2) encapsulated by two
                      graphene sheets. The hybrid membrane shows high quality
                      factors up to 245,000 at low temperatures, comparable to the
                      best few-layer graphene mechanical resonators. In contrast
                      to few-layer graphene resonators, the device shows reduced
                      electrical losses attributed to the lower resistivity of the
                      NbSe2 layer. The peculiar low-temperature dependence of the
                      intrinsic quality factor points to dissipation over
                      two-level systems which in turn relax over the electronic
                      system. Our high sensitivity readout is enabled by coupling
                      the membrane to a superconducting cavity which allows for
                      the integration of the hybrid mechanical resonator as a
                      sensitive and low loss transducer in future quantum
                      circuits.},
