A device fabricated from conventional fractional quantum Hall states and s-wave superconductors that supports exotic non-defects binding parafermionic zero modes, which generalize Majorana bound states are introduced.
Universal topological quantum computation from a superconductor/Abelian quantum Hall heterostructure
Non-Abelian anyons promise to reveal spectacular features of quantum mechanics that could ultimately provide the foundation for a decoherence-free quantum computer. A key breakthrough in the pursuit…

This work considers the effect of a magnetic field on a spin model--the toric code--which is in a topological phase, and shows how the topological order breaks down when the system is coupled to an Ohmic heat bath.
Spin transfer of quantum information between Majorana modes and a resonator.
