Adiabatic quantum simulation with a segmented ion trap: Application to long-distance entanglement in quantum spin systems

Understand

We investigate theoretically systems of ions in segmented linear Paul traps for the quantum simulation of quantum spin models with tunable interactions.

• The scheme is entirely general and can be applied to the realization of arbitrary spin-spin interactions.
• As a specific application we discuss in detail the quantum simulation of models that exhibit long-distance entanglement in the ground state.
• We show how tailoring of the axial trapping potential allows for generating spin-spin coupling patterns that are suitable to create long-distance entanglement.
