What sets IonQ apart
In October 2025, IonQ reported a 99.99% two-qubit gate fidelity, the first quantum computing company to publish a result past the "four-nines" threshold, alongside a stated 256-qubit system demonstration for 2026 and a roadmap to 2 million qubits by 2030.
Three other facts set it apart from most quantum computing employers:
- The largest publicly-traded pure-play trapped-ion quantum computing company, trading on the NYSE as IONQ since October 2021 after a SPAC merger with dMY Technology Group III
- Founded in 2015 on trapped-ion research from Chris Monroe's University of Maryland lab and Jungsang Kim's Duke University lab
- Its acquisition of Oxford Ionics, the previous fidelity record-holder, put both laser-driven and microwave-driven qubit control approaches under the same roof
A hardware or applications hire here works inside one of only two organizations that have published a fidelity result at this level, and does so under a public company's quarterly reporting cadence rather than a private-stage competitor's - the roadmap milestones above are commitments made to shareholders, not just an internal engineering target.
