Realisation of homogeneous ion chain using surface traps

In a Radio-Frequency linear ion trap, 1D ion chains are routinely generated in laboratories around the world. They present a non-homogenous ion density along the chain. The possibility of generating uniformly distributed ion chain, where the distance between any adjacent ions is a constant, would open up new type of experiments in the context of Quantum Information and in the study of the Homogeneous Kibble-Zurek mechanism.
