Rice’s atom trap glowed where it shouldn’t

An October 13 paper traces the redesign to tiny gaps separating its electrodes.
Rice University researchers built a tiny gold-coated glass device to hold charged atoms with electric fields. Their first design developed glowing hot spots under high voltage. The team’s October 13 paper explains how later designs widened the trenches between electrodes and changed them from L-shaped to U-shaped. The glow disappeared in subsequent tests.
Heat also needed an escape route: ceramic layers connected to aluminum heat sinks carried it away. The third-generation trap was tested with ytterbium ions. These are laboratory results from Rice and its collaborators, not a demonstration of a consumer quantum computer.
