Abstract
Recent experiments have shown that arrays of miniature ion traps are a viable technology for scalable quantum information processing, and this has led to considerable interest in the development of microtrap technology. There are, however, several problems associated with the miniaturisation of ion traps. One of the most significant of these is the rapid increase in heating rate that is observed as the trap size is reduced. This heating is attributed to patch potentials due to contaminants on the trap electrodes. There is experimental evidence to suggest that cooling of the electrodes to low temperatures can suppress this effect.[1]
