IonQ Demonstrates Telecom-Wavelength Conversion to Enable Quantum Links Over Standard Fiber

An AFRL-backed prototype converts barium-ion photons for fiber transmission to accelerate tests of networked quantum systems.

Overview

  • IonQ reported converting visible photons from its trapped-ion systems into telecom wavelengths on a prototype device.
  • The company said the effort with the Air Force Research Laboratory advances long-distance interconnects for its quantum machines.
  • CEO Niccolo de Masi said IonQ will soon link two quantum computers over standard wavelengths using commercial fiber.
  • IonQ shares rose roughly 3% to about $74 after the announcement, extending a recent rally.
  • The networking push builds on acquisitions in QKD and hardware—Lightsynq, Capella, ID Quantique, Qubitekk and the announced Oxford Ionics deal—and a new Department of Energy partnership on space use cases.
