TRAPPED-ION QUANTUM SIMULATOR

Coherent manipulations involving the quantized motional and internal s tates of a single trapped ion can be used to simulate the dynamics of other systems. We consider some examples, including the action of a Ma ch Zehnder interferometer which uses entangled input states. Coherent manipulations can also be used to create entangled states of multiple trapped ions; such states can be used to demonstrate fundamental quant um correlations.
