Atom Computing, Diraq, IBM and IonQ Advance to DARPA QBI Stage C
DARPA has moved Atom Computing, Diraq, IBM, and IonQ into the final Stage C of its Quantum Benchmarking Initiative, shifting their proposed systems into hands-on government verification and validation. The four teams represent distinct qubit modalities: Atom Computing's neutral atoms, Diraq's silicon CMOS spin qubits, IBM's superconducting processors, and IonQ's trapped ions.

If Stage C completes on schedule and DARPA publishes at least summary results, this could within two years give defense and enterprise buyers the first apples-to-apples, government-validated comparison of neutral-atom, spin-qubit, superconducting, and trapped-ion systems against a defined utility threshold.
The four selected vendors span four different qubit modalities and are now entering hands-on evaluation against DARPA's Quantum Benchmarking Initiative utility metrics, so the output would be the first independent cross-platform benchmark of this scale.
