    "abstract": "We show how an experimentally realized set of operations on a single trapped\nion is sufficient to simulate a wide class of Hamiltonians of a spin-1/2\nparticle in an external potential. This system is also able to simulate other\nphysical dynamics. As a demonstration, we simulate the action of an $n$-th\norder nonlinear optical beamsplitter. Two of these beamsplitters can be used to\nconstruct an interferometer sensitive to phase shifts in one of the\ninterferometer beam paths. The sensitivity in determining these phase shifts\nincreases linearly with $n$, and the simulation demonstrates that the use of\nnonlinear beamsplitters ($n$=2,3) enhances this sensitivity compared to the\nstandard quantum limit imposed by a linear beamsplitter ($n$=1).",
