Title: Physics, quantum computing, ion trap
Description: The NIST X-trap is constructed from a sandwich of two diamond-shaped alumina wafers, visible in the right center of the first photo. The second photo shows a close-up of the wafers. Ions are created in the lower left portion of the dark grey channel, which is a trench cut through both wafers. By controlling voltages on the 46 electrodes, the ions can be shuttled along the channels and through the junction between the two gold-coated bridges that form the X while remaining much cooler than in previous experiments.
