QuEra expands multi-year AWS collaboration for fault-tolerant quantum

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.

2:1 physical-to-logical qubit ratio (with Harvard/MIT)

Reached

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.
