Quantum simulations with cold trapped ions

Thomas Monz, R. Blatt

Summary form only given. Strings of trapped ions are applied to investigate the dynamics and propagation of entanglement in an analogue fashion. With a small trapped-ion quantum computer a digital quantum simulation of a lattice gauge theory is performed.

This paper summarizes some important achievements of quantum information processing with trapped ions or neutral atoms. In particular, we describe the storage of information and realization of two-qubit gates with ions, as well as the creation of entanglement and quantum simulation with cold atoms in optical lattices.

Gauge theories such as quantum electrodynamics, in principle, give us a precise understanding of the interactions between subatomic particles, but often the calculations involved are beyond current computational capabilities. Quantum simulators based on experimental many-body systems could be a solution to this problem. Scientists exploit the current state-of-the-art experimental technology for manipulating cold trapped ions and propose a simulator of the one-dimensional version of quantum electrodynamics.
