N2 - We show that weak antilocalization by disorder competes withresonant Andreev reflection from a Majorana zero mode to produce a zerovoltageconductance peak of order e^2/h in a superconducting nanowire. Thephase conjugation needed for quantum interference to survive a disorderaverage is provided by particle–hole symmetry—in the absence of timereversalsymmetry and without requiring a topologically nontrivial phase. Weidentify methods of distinguishing the Majorana resonance from the weakantilocalization effect.
