Ion Trapping: Scientific & Technological Challenges

Electric Field Noise & Trap Miniaturization
Electric Field Noise & Trap Miniaturization Ion traps provide an excellent tool for controlling and observing the state of trapped ions. Recently, miniaturization has added greatly to the trap functionalities such as speed of the quantum operations and, more importantly, to scaling to larger number of individually controlled quantum bits. However there are some short-comings associated…
Light-Induced Charging of Ion Trap’s Electrodes
Light-Induced Charging of Ion Trap’s Electrodes The typical trapped ion-to-metal electrode distance in a surface microtrap is on the order of 10–100 microns. This close-proximity makes the trapped ions sensitive to surface effects such as electric-field noise and localized charging of the trap electrodes or of the substrate. The Chuang group at MIT studied the light-induced…
Ion Traps with Integrated Optics
Ion Traps with Integrated Optics Since their first appearance in the 1990’s, ion trap chips have evolved from a novelty into powerful experimental tools used by leading research groups. Yet, ion trap microfabrication is still in its infancy phase; many more technological advances are necessary before ion microtraps are widely used outside specialized laboratories. One…
Exposed Dielectrics
Exposed Dielectrics Insulating materials (dielectrics) can accumulate charges that are hard to dissipate and drift slowly over time. Such materials when present in or near trapped ions can thus frustrate efforts to obtain a well-controlled trapping potential. A common approach is therefore to avoid insulating materials in the vicinity of the ion.…
