IonQ and IBM have advanced to Stage C of DARPA's Quantum Benchmarking Initiative, which provides up to $300 million in funding to develop commercially viable fault-tolerant quantum computers by 2033. IonQ leads in accuracy with 99.99% 2-qubit gate fidelity and recent quantum error-correction breakthroughs, while IBM pursues a faster superconducting qubit approach with ambitious plans for a fault-tolerant system by 2029.
Axe note: DARPA’s backing of IonQ and IBM highlights potential, yet local impact remains distant for now.
