Summary
Libra is designed to execute about 1 million reliable logical quantum operations, marking QuEra’s first planned fault-tolerant system for Amazon Web Services.
The machine is projected to include more than 256 error-corrected logical qubits and a 10^-6 logical error rate, metrics aimed at moving beyond today’s noisy quantum hardware.
QuEra said the architecture builds on eight peer-reviewed papers with Harvard and MIT showing logical qubits, below-threshold error correction and other core fault-tolerance capabilities.
The expanded multi-year AWS partnership would make the system cloud-accessible through Amazon’s quantum stack, with QuEra already testing successive internal generations ahead of the 2028 delivery.
