  • Fractional quantum statistics has recently been identified in quantum transport experiments, but the entanglement that may be associated with it remains elusive. Here the authors theoretically and experimentally investigate statistics-induced entanglement in an anyonic collider with Andreev-like tunnelling.

  • Measuring quantum entanglement remains a demanding task. The authors introduce two functions to quantify entanglement induced by fermionic or bosonic statistics, in transport experiments. Both functions, in theory and experiment, are remarkably resilient against the nonuniversal effects of interactions.

  • The authors extend the theory of quantum conductance corrections to 2D electron systems with the symplectic symmetry, such as topological-insulator surface states. They find that magnetoconductance can be enhanced significantly by second-order interference and electron-electron interaction effects.

  • The Josephson effect is at the core of superconducting devices. Here, the authors demonstrate control of spatial confinement, amplitude, and density profile of supercurrents in one-dimensional nanoscale constrictions within graphene bilayers.
