We discuss systems of ions in segmented linear Paul traps for the quantum simulation of spin models which exhibit long-distance entanglement (LDE) in the ground state. The axial potential can be tailored to create different coupling patterns suitable to create LDE in quantum spin chains. Microwave pulses are used to implement various kinds of spin-spin interaction Hamiltonians, which can be varied adiabatically thereby realizing the adiabatic preparation of the ground states of quantum spin Hamiltonians exhibiting LDE.
