Quantum electronics with trapped ions
An oscillating trapped ion induces oscillating image charges in the trap electrodes. If this current is send to the electrodes of a second trap, it influences the motion of an ion in the second trap. The expected time for a complete exchange of the ion motions is 1 ms for a trap with a characteristic size of 50 μm. This inter-trap coupling may be used for scalable quantum computing, cooling ion species that are not directly accessible to laser cooling, for the non-invasive study of superconductors, and for coupling an ion-trap quantum computer to a solid-state quantum computer, e.g. a system of Josephson junctions.
