    "abstract": "Sub-Planck phase-space structures in the Wigner function of the motional\ndegree of freedom of a trapped ion can be used to perform weak force\nmeasurements with Heisenberg-limited sensitivity. We propose methods to\nengineer the Hamiltonian of the trapped ion to generate states with such small\nscale structures, and we show how to use them in quantum metrology\napplications.",
