Fault-tolerant by 2028
Amazon Web Services and QuEra Computing say they plan to make a fault-tolerant quantum computer available through Amazon Braket in 2028, with QuEra’s Libra system designed as a Megaquop-scale fault-tolerant quantum computer capable of performing approximately 1 million logical quantum operations.
“Quantum computing news usually picks up near the end of the year, as companies try to provide evidence that they are hitting benchmarks on time”
Ars TechnicaQuEra said the planned system will feature more than 256 error-corrected logical qubits and a logical error rate of 10⁻⁶, specifications it says are needed to support computations at that scale.
Ars TechnicaSpeaking to SDxCentral at Commercialising Quantum Global 2026 in London, Tommaso Macrì, senior director of business development at QuEra, said, "The field has evolved from analog to digital, in particular from physical qubits to logical qubits."
The announcement extends a relationship that began in 2022 when QuEra’s Aquila system became the first neutral-atom quantum computer available through Amazon Braket, and Macrì said the remaining challenge is integrating those capabilities into a production system that can operate reliably for extended periods.
AWS cloud, error correction
In parallel, 디지털투데이 says AWS is teaming up with U.S. quantum computing startup QuEra Computing to commercialise fault-tolerant quantum computers, aiming to introduce a system with error-correction functions to the AWS cloud within the next 2 years.
The same report says the collaboration’s central focus is error-control technology, described as the biggest obstacle to commercialising quantum computing, because qubits are highly sensitive to changes in the surrounding environment.
디지털투데이 also quotes QuEra chief scientific officer Mikhail Lukin saying, "The dream of realising a useful fault-tolerant quantum computer has for the first time become a realistic goal."
It adds that QuEra’s neutral-atom approach uses arrays of individual atoms manipulated with optical tweezers, and that the companies plan to unveil Libra as a MegaQuOp-class system supporting hundreds of error-corrected logical qubits.
Roadmaps and quantum stakes
While AWS and QuEra set a 2028 target for fault-tolerant quantum computing, Ars Technica frames the timeline as unusually soon, noting that many people in the field expect useful quantum computers are still about five to 10 years away.

Ars Technica says useful computations will require some form of error correction enabled by linking hardware qubits into logical qubits, and it describes logical qubits as including redundant storage of information along with neighboring qubits that can be measured to determine when errors occur and how to fix them.
In a separate quantum roadmap push, ITforBusiness.fr reports that Infleqtion finalized a 1600-qubit processor built with neutral atoms and published a roadmap intended to drive Deeptech toward an enterprise-grade quantum computer by the end of 2028.
ITforBusiness.fr quotes Scott Faris, CEO of Infleqtion, saying, "2024 is a turning point for quantum technologies," and it says the roadmap begins with the 2024 availability of its 1600-qubit machine and its software platform Superstaq.
