  • Gatemons, or gate-tunable transmons, are superconducting qubits based on hybrid Josephson junctions, which typically use extended quantum conductors as weak links. Here the authors report a gatemon made with a carbon-nanotube-based junction, showing improved coherence time compared to graphene-based devices.

  • Bilayer graphene nanoribbons are very promising for future nanoelectronics. Here Lopes et al.show a novel approach for the fabrication of quasi-free-standing bilayer graphene nanoribbons on SiC, based on the precise control of the layer-by-layer growth of graphene and a simple annealing step in air.

  • In order to use nuclear spins for the creation of qubits, an efficient nuclear spin hyperpolarisation at room temperature is crucial. Here the authors show how this can be achieved by spin polarized conduction-band electrons in a semiconductor, exploiting the defect-engineered spin-filtering effect.
