Roadmap & milestones
96 logical qubits
2026-01QuEra / Harvard
Fault-tolerant architecture running algorithms on up to 96 logical qubits.
2:1 physical-to-logical qubit ratio (with Harvard/MIT)
2026-04QuEra / 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.
