Physical realization of topological quantum walks on IBM-Q and beyond
Radhakrishnan Balu, Daniel Castillo, George Siopsis
We discuss an efficient physical realization of topological quantum walks on a finite lattice. The -point lattice is realized with qubits, and the quantum circuit uti…

Continuous-time limit of topological quantum walks
Radhakrishnan Balu, Daniel Castillo, George Siopsis +1
We derive the continuous-time limit of discrete quantum walks with topological phases. We show the existence of a continuous-time limit that preserves their topological phases. We…
