Overview
- IonQ reports 99.99% two‑qubit gate fidelity, a measure of how often a two‑qubit operation works as intended, placing it at the front of reported accuracy claims.
- IonQ builds trapped‑ion systems using ytterbium and, after buying Oxford Ionics, shifted from laser steering to microwave signals built into its chips to shrink and toughen its machines.
- Yahoo Finance reports IonQ is moving toward vertical integration through a proposed purchase of SkyWater Technology to speed chip prototyping and future scaling.
- Rival Infleqtion uses neutral rubidium and cesium atoms and reports 99.73% two‑qubit fidelity, while promoting sensing products such as its Tiqker atomic clock and quantum inertial sensors sold to NASA and the U.S. Navy.
- Both articles note that broad, practical quantum computing remains years away even as interest from big tech firms and public‑market investors rises.
