Ankaa-3 — 84 qubits at 99.5% 2-qubit fidelity

Rigetti Computing — Rigetti launched its 84-qubit Ankaa-3 superconducting system with a 99.5% median two-qubit gate fidelity — a major reliability jump from a redesigned qubit layout and Alternating-Bias Assisted Annealing, available on Rigetti's cloud and later AWS Braket / Azure.
