Realizing universal topological quantum gates in simulated time-reversal-invariant superconducting chains

We propose a topology-preserved hard-core boson simulator of one-dimensional time-reversal-invariant topological superconductor. By using the developed dispersive dynamic modulation approach, not only the faithful simulation of this DIII type of spinful superconducting chains is achieved, but also a set of universal topological quantum gates can be realized. 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.
