"placed graphene domain walls (highly conductive) between 2 superconductors, achieving ultimate proximity between counterpropagating edge states while minimizing effects of disorder... supercurrents at temperatures up to 1°K at high magnetic fields... gate voltage propagates in 2 opposite directions within same nanoscale space without scattering... standing electron waves modulate superconducting in quantum Hall regime... topological quasiparticles combining the quantum Hall effect and superconductivity"
