Overview
- IonQ, which disclosed Tuesday it was selected for DARPA’s HARQ program, saw its shares rise about 10 percent.
- HARQ aims to create networked quantum computers by joining different qubit types into one working system.
- IonQ will develop high-speed interconnects that let trapped-ion, neutral-atom, and superconducting devices exchange quantum information.
- The company plans quantum memory chips made from synthetic diamond to store and relay entanglement between nodes.
- Photonic integration will move information as light so cross-platform links maintain speed and signal fidelity.
