Given the advances made in trapped-ion quantum information processing, ions make a natural choice of physical qubit in a register. By contrast, the ability to reliably transmit light over long distances makes photons a natural choice for flying qubits to connect the registers. It may be possible to couple these two systems by trapping ions in the evanescent field of a nanofibre.
Implementation of such an ion-fibre system is not without technical and physical challenges, particularly with regard to positional stability, and ion heating close to nanostructures. We describe an ion trap / nanofibre system used to investigate such effects, and propose methods of observing coupling between ions and evanescent waves, even in the presence of such perturbations.
