Abstract
A system of two parallel constrictions in a two-dimensional hole gas h as been studied. At zero magnetic-field conductance quantization is ob served through the individual constrictions. At high magnetic fields A haronov-Bohm oscillations result from resonant tunneling through state s encircling the repulsive potential between the constrictions. The os cillations demonstrate directly phase-coherent transport of holes.
