DARPA moves four quantum systems to final stage of benchmark

DARPA said quantum systems from IBM, Atom Computing, IonQ and Australia's Diraq have passed Stage B of its Quantum Benchmarking Initiative and advanced to Stage C. There they will join systems from Microsoft and PsiQuantum to assess whether they can be deployed at utility scale by 2033.

• IBM, Atom Computing, IonQ and Diraq passed Stage B of DARPA's benchmark
• Microsoft and PsiQuantum systems will join them in Stage C
• The program assesses utility-scale deployment by 2033
• The systems use different qubit approaches, including superconducting and silicon spin qubits
