Scientists achieve strong light-sound coupling in an optical fiber

For the first time, researchers achieved strong coupling between light and long-lived acoustic vibrations in an optical fiber. Published in Nature Physics, the work could let fibers act as quantum processors, not just links between computing nodes, advancing quantum signal processing.

• First strong coupling of light and long-lived acoustic vibrations in an optical fiber
• Results published in the journal Nature Physics
• Fibers could one day serve as quantum processors, not only as links
• Work paves the way for new quantum signal processing technologies
