Today in @nature, Laboratory researchers describe a new way to deliver laser light to ion-trap systems, a leading platform for future quantum computers. The technology delivers light directly into the ion trap instead of using free-space optics.
Lighting up the ion trap
Fiber optics built into a chip can deliver all the laser light needed to control ions for quantum computing and sensing.
