Frank Pollmann (TU Munchen, Munich Center for Quantum Science and
Technology): Exploring Topological Phases on Quantum Processors

Universal quantum computers are potentially an ideal setting for simulating
emergent quantum many-body phenomena that are out of reach for classical
computers. Here we discuss two applications to the study of topologically
ordered systems: First, we represent the ground states of Hamiltonians
using shallow quantum circuits and observe a quantum phase transition
between different symmetry-protected topological phases on a quantum
device. Second, we prepare the ground state of the toric code Hamiltonian
using an efficient quantum circuit on a superconducting quantum processor.
We measure a topological entanglement entropy near the expected value of ln
2, and simulate anyon interferometry to extract the braiding statistics of
the emergent excitations.
