Trapped-ion maker; first to a 99.99% two-qubit gate. Acquired Oxford Ionics (2025).
IonQ received final regulatory approval to acquire chip foundry SkyWater Technology ($35/share, cash-and-stock), closing July 31. It secures a fully domestic semiconductor supply chain — SkyWater's Minnesota, Florida and Texas fabs and advanced packaging — making IonQ, it says, the only vertically integrated full-stack quantum company.
IonQ — IonQ launched Clavis XG Multiplex, letting quantum-key-distribution traffic run alongside classical data on existing metropolitan fiber — so operators need not redesign, isolate or dedicate optical networks for quantum security. Paired with its Clarion KX key-exchange platform, it targets the "harvest-now, decrypt-later" threat and aims to move customers from QKD pilots to production deployment.
IonQ — IonQ sold its first 6th-gen, chip-based 256-qubit system (to the University of Cambridge) and posted record Q1 revenue of $64.7M (+755% YoY); its roadmap targets 10,000 networked qubits.
99.9% vs 99.99% looks like a rounding error but means 10× fewer mistakes. Error correction only pays off above a threshold near “three nines”; crossing “four nines” buys real headroom.
