IonQ Shows Prototype That Converts Visible Photons to Telecom Wavelengths for Quantum Networking

The company says frequency conversion will let its trapped‑ion systems link over existing fiber.

Overview

  • IonQ reported a prototype that converts photons from visible wavelengths used with trapped barium ions into telecom bands.
  • The demonstration was conducted with research support from the Air Force Research Laboratory, according to the company.
  • IonQ said the advance paves the way to interconnect quantum computers over commercial fiber, with the CEO saying two systems will be linked soon.
  • Shares rose about 3% on Sept. 23 after the news, extending a multi‑day rally that included an eight‑day winning streak and pushed market value to roughly $18 billion, according to market reports.
