  • Using the valley degree of freedom in analogy to spin to encode qubits could be advantageous as many of the known decoherence mechanisms do not apply. Now long relaxation times are demonstrated for valley qubits in bilayer graphene quantum dots.

  • Superconducting giant atoms are realized in a waveguide by coupling small atoms to the waveguide at multiple discrete locations, producing tunable atom–waveguide coupling and enabling decoherence-free interactions.

  • A single electron quantum dot in bilayer graphene is a candidate for a spin-valley qubit, however its excited state spectrum has not been determined under relevant conditions. Here the authors accomplish this using time-resolved charge detection technique and set the new upper bound on the inter-valley mixing.
