## Description

- description: We show ballistic superconductivity in InSb semiconductor nanowires.
    Our structural and chemical analyses demonstrate a high-quality interface between
    the nanowire and a NbTiN superconductor. The high-quality interface enables ballistic
    transport manifested by a quantized conductance for normal carriers, and a strong
    enhancement of conductance resulting from Andreev reflection. Gate tuning the
    device to a tunnel probe reveals an induced hard-gap with a significantly reduced
    subgap density of states, corroborating the homogeneity of our hybrid interface.
    These results constitute a substantial improvement in induced superconductivity
    in semiconductors, and pave the way for disorder-free Majorana devices.
