  We propose two experimental setups that allow for the implementation and the
detection of fractional solitons of the Goldstone-Wilczek type. The first setup
is based on two magnetic barriers at the edge of a quantum spin Hall system for
generating the fractional soliton. If then a quantum point contact is created
with the other edge, the linear conductance shows evidence of the fractional
soliton. The second setup consists of a single magnetic barrier covering both
edges and implementing a long quantum point contact. In this case, the
fractional soliton can unambiguously be detected as a dip in the conductance
without the need to control the magnetization of the barrier.
