Majorana zero modes in iron-based superconductors can spread across several fractional vortex cores rather than sitting at a single point. That spread would let researchers detect them with both local tunneling and a nonlocal method called crossed Andreev reflection, giving the field a second way to confirm the particles that topological qubits depend on. The approach is still early, so the key questions are whether experiments reproduce these signatures and whether they can be told apart from non-topological explanations.
