I will introduce a new platform based on spin transitions in the
fractional quantum Hall effect regime where parafermions - higher
order non-abelian excitations - can be realized. Local (gate)
control of spin transition allows formation of isolated domain
walls, which consist of counter-propagating edge states of opposite
polarization with fractional charge excitations. When
superconductivity is induced into such a domain wall from
superconducting contacts via proximity effect, parafermions are
expected to be formed at the domain wall boundaries. In a
multi-gate device a re-configurable network of domain walls can be
formed allowing creation, braiding, manipulation and fusion of
parafermions. In respect to the quantum computing application
parafermons are more computationally intense than Majoranas and are
a building block for Fibonacci fermions, even high order
non-Abelian particles that can perform universal gate operations
within the topologically protected subspace.
