National Physical Laboratory (NPL) researchers have developed a monolithic three-dimensional (3D) ion microtrap array that could be scaled up for use in quantum computing to run quantum algorithms.

The researchers say the device can be embedded in a semiconductor chip, confining individual ions at the nanoscale. The 3D ion-trapping device is based on maintaining the ability to scale the device to accommodate increasing numbers of atomic particles while preserving the trapping potential, which enables precise control of ions at the atomic level. The monolithic ion microtrap combines a near ideal 3D geometry with a scalable fabrication process.

The researchers developed the microtrap device from a silica-on-silicon wafer, and the fabrication process should allow the device to handle many more ions while retaining the ability to individually control each of them. "We managed to produce an essential device or tool, which is critical for state-of-the-art research and development in quantum technologies," says NPL researcher Alastair Sinclair.
