Abstract
We realize fast transport of ions in a segmented microstructured Paul trap. The ion is shuttled over a distance of more than times its ground state wave function size during only five motional cycles of the trap ( in ). Starting from a ground-state-cooled ion, we find an optimized transport such that the energy increase is as low as motional quanta. In addition, we demonstrate that quantum information stored in a spin-motion entangled state is preserved throughout the transport. Shuttling operations are concatenated, as a proof-of-principle for the shuttling-based architecture to scalable ion trap quantum computing.

Moving Traps Offer Fast Delivery of Cold Ions
Published 20 August 2012
Two separate experiments have demonstrated the fast transport of trapped ions using trapping potentials that trace out the path for the ions to follow.
