## Description

- description: Inducing superconducting correlations in chiral edge states is predicted
    to generate topologically protected zero energy modes with exotic quantum statistics.
    Experimental efforts so far have focused on engineering interfaces between superconducting
    materials—typically amorphous metals—and semiconducting quantum Hall or quantum
    anomalous Hall systems. However, the strong interfacial disorder inherent in this
    approach can prevent the formation of isolated topological modes. An appealing
    alternative is to use low-density flat band materials in which the ground state
    can be tuned between intrinsic superconducting and quantum anomalous Hall states
    using only the electric field effect. However, quantized transport and superconductivity
    have not been simultaneously achieved. Here we show that rhombohedral tetralayer
    graphene aligned to a hexagonal boron nitride substrate hosts a quantized anomalous
    Hall state at superlattice filling ν = −1 as well as a superconducting state at
    ν ≈ −3.5 at zero magnetic field. Gate voltage can also be used to actuate non-volatile
    switching of the chirality in the quantum anomalous Hall state, allowing, in principle,
    arbitrarily reconfigurable networks of topological edge modes in locally gated
    devices. Thermodynamic compressibility measurements further show a topologically
    ordered fractional Chern insulator at ν = 2/3 —also stable at zero magnetic field—enabling
    proximity coupling between superconductivity and fractionally charged edge modes.
    Finally, we show that, as in rhombohedral bi- and trilayers, integrating a transition
    metal dichalcogenide layer to the heterostructure nucleates a new superconducting
    pocket, while leaving the topology of the ν = −1 quantum anomalous Hall state
    intact. Our results pave the way for a new generation of hybrid interfaces between
    superconductors and topological edge states in the low disorder limit.
