Query: Coherent transport through a Majorana island in an Aharonov-Bohm
  interferometer   Majorana zero modes are leading candidates for topological quantum
computation due to non-local qubit encoding and non-abelian exchange
statistics. Spatially separated Majorana modes are expected to allow
phase-coherent single-electron transport through a topological superconducting
island via a mechanism referred to as teleportation. Here we experimentally
investigate such a system by patterning an elongated epitaxial InAs-Al island
embedded in an Aharonov-Bohm interferometer. With increasing parallel magnetic
field, a discrete sub-gap state in the island is lowered to zero energy
yielding persistent 1e-periodic Coulomb blockade conductance peaks (e is the
elementary charge). In this condition, conductance through the interferometer
is observed to oscillate in a perpendicular magnetic field with a flux period
of h/e (h is Planck's constant), indicating coherent transport of single
electrons through the islands, a signature of electron teleportation via
Majorana modes, could also be observed, suggesting additional non-Majorana
mechanisms for 1e transport through these moderately short wires.
