Talk Title: Probing Majorana edge states with a flux qubit A pair of counter-propagating Majorana edge modes appears in chiral
p-wave superconductors and in other superconducting systems belonging to the
same universality class. These modes can be described by an Ising conformal
field theory. We show how a superconducting flux qubit attached to such a
system couples to the two chiral edge modes via the disorder field of the Ising
model. Due to this coupling, measuring the back-action of the edge states on
the qubit allows to probe the properties of Majorana edge modes. |
