The existence of Majorana zero modes have been potentially confirmed in superconductor-semiconductor nanowires but recent studies suggest the data can also be interpreted using Andreev bound states, throwing into doubt the conclusions regarding Majorana modes. To resolve this controversy the authors use non-Hermitian topology to determine the boundaries between the Majorana and Andreev states.
