  One-dimensional time-reversal invariant topological superconducting wires of
the symmetry class DIII exhibit exotic physics which can be exploited to
realize the set of universal operations in topological quantum computing.
However, the verification of DIII-class physics in conventional condensed
matter materials is highly nontrivial due to realistic constraints. Here we
propose a symmetry-protected hard-core boson simulator of the one-dimensional
DIII topological superconductor. By using the developed dispersive dynamic
modulation approach, not only the faithful simulation of this new type of
spinful superconducting chains is achieved, but also a set of universal quantum
gates can be realized with the computational basis formed by the degenerate
ground states that are topologically protected against random local
perturbations. Physical implementation of our scheme based on a Josephson
quantum circuit is presented, where our detailed analysis pinpoints that this
scheme is experimentally feasible with the state-of-the-art technology.
