| Summary:
The realization of novel phases of matter on quantum simulators is a topic of
intense interest. Digital quantum computers offer a route to prepare
topological phases with interactions that do not naturally arise in analog
quantum simulators. Here, we report the realization of symmetry-protected
topological (SPT) phases of a spin-{1/2} Hamiltonian with next-nearest-neighbor
hopping on up to 11 qubits on a programmable superconducting quantum processor.
We observe clear signatures of the two distinct SPT phases, such as excitations
localized to specific edges and finite string order parameters. Our work
advances ongoing efforts to realize novel states of matter with exotic
interactions on digital near-term quantum computers.
