Neutral-atom, Harvard-linked; ran algorithms on up to 96 logical qubits (2026).
Error correction stopped being a promise in 2026 — 96 logical qubits, an 800× logical-to-physical gap, a 2:1 encoding ratio. The machine that breaks RSA still needs thousands of logical qubits. A read of every quantum number this tracker holds.
QuEra announced an expanded multi-year strategic collaboration with AWS to host its planned fault-tolerant “Libra” system natively on Amazon Braket — a concrete agreement (confirmed by AWS) alongside a 2028, 256-logical-qubit roadmap.
QuEra / Harvard / MIT — QuEra, Harvard and MIT showed qLDPC codes encoding 1,156 logical qubits into 2,304 physical (≈2:1, >50% rate), simulated into the "teraquop" regime (~1 error per trillion ops) — versus the hundreds-to-one ratio typical today.
QuEra / Harvard — Fault-tolerant architecture running algorithms on up to 96 logical qubits.
Harvard / QuEra — First programmable logical processor running algorithms on dozens of error-corrected qubits.
