Quantum transport in superconductors remains difficult to study due to the typically small Fermi wavelength. Here, Thierschmann et al. demonstrate a superconducting quantum point contact with split gate technology at the superconducting LaAlO3/SrTiO3 interface and, due to its two-dimensionality, identify three regimes of quantum transport.
