Researchers demonstrate integrated stabilized laser chips performing clock and quantum operations on a room temperature trapped ion qubit
Researchers from UC Santa Barbara and University of Massachusetts Amherst have demonstrated a chip-scale, stabilized visible-light laser system that can operate a trapped-ion optical atomic clock and quantum qubit at room temperature, advancing the push toward compact and portable quantum technologies. The work, published in Nature Communications and led in part by IEE's Daniel Blumenthal, integrates ultra-low-noise photonic lasers and stabilization components onto chips to replace traditionally bulky, table-top optical systems.
