  We propose an interferometer for chiral Majorana modes where the interference
effect is caused and controlled by a Josephson junction of proximity-induced
topological superconductors, hence, a Majorana-Josephson interferometer. This
interferometer is based on a two-terminal quantum anomalous Hall bar, and as
such its transport observables exhibit interference patterns depending on both
the Josephson phase and the junction length. Observing these interference
patterns will establish quantum coherent Majorana transport and further provide
a powerful characterization tool for the relevant system.
