Mike Brownnutt wants to know how to scale up quantum computers. It is currently possible to realise basic quantum operations with about ten ions. However, just putting lots of these systems together brings technical and fundamental problems, which prevents us from going to 20 ions (let alone a million ions) without radically rethinking what we do. Scaling traps to hold more ions (in 1D and then in 2D) requires new ways of creating and changing the trap potentials. Miniaturising traps puts (cold, charged) ions to be closer to the (hot) electrodes and (unpredictable) dielectrics. This necessitates cryogenic traps and further research. These projects are at exciting interdisciplinary boundaries of quantum mechanics, surface science, and electronics.
