QuEra to launch Libra quantum computer on AWS in 2028

QuEra will launch its Libra fault-tolerant quantum computer on Amazon Braket in 2028 under an expanded multi-year collaboration with AWS.

Libra is designed to provide more than 256 error-corrected logical qubits and about one million reliable logical quantum operations. QuEra says that level of error correction is intended to support early commercial and research workloads through cloud access on Amazon Braket.

Fault-tolerant quantum computing is widely seen as a key hurdle for the sector because current machines are prone to errors that limit the length and usefulness of calculations. QuEra is positioning Libra as a system that moves beyond those constraints for work in areas such as drug discovery, materials research, optimisation, and scientific computing.

AWS is expanding a relationship with QuEra that began when QuEra's Aquila system became available on Amazon Braket in 2022. Under the new arrangement, Libra would become the first fault-tolerant system from QuEra available through the AWS quantum service.

QuEra's approach is based on neutral-atom quantum computing, a field in which it has already deployed Aquila, a 256-physical-qubit machine, and Gemini, a system with logical-qubit features co-located with the ABCI-Q supercomputer in Japan. According to QuEra, the Libra design has been validated through peer-reviewed research.

That research record is central to QuEra's pitch to customers and partners. Teams at QuEra and in the laboratories of its scientific founders at Harvard and MIT have published eight peer-reviewed papers in Nature and Physical Review Letters covering the building blocks behind the Libra architecture.

The published results include work on logical qubits, below-threshold error correction, transversal logical operations, fast decoding for real-time error correction, sustained operation of thousands of qubits with continuous atom reloading, and error-correcting codes intended to reduce the physical-qubit cost of each logical qubit. QuEra says these elements underpin its roadmap towards a fault-tolerant machine available through the cloud.

"Fault-tolerant quantum computing is moving from a scientific milestone to an engineering and deployment roadmap," said Andy Ory, chief executive officer of QuEra Computing.

"We have executed this roadmap in the open, with peer-reviewed milestones and validated system advances. Libra brings fault-tolerant computing to the cloud at scale in 2028. It is an important step forward, and subsequent generations will scale even further, as we will reveal in our roadmap webinar later this month. We are inviting leaders to engage now so they can build the talent, use cases, and workflows needed to be ready when these systems come online," Ory said.

Cloud access

Amazon Braket is AWS's managed quantum computing service, allowing users to develop and run quantum programs alongside conventional computing resources. AWS says integrating QuEra's system into that environment would let customers combine quantum processors with existing high-performance computing and artificial intelligence tools.

"We believe fault-tolerant quantum computing will become a foundational part of how customers solve their hardest computational problems on AWS. QuEra's technology has demonstrated a clear path to that future. By bringing these capabilities to customers through Amazon Braket, they can combine QuEra's fault-tolerant quantum processors with the scalable AWS HPC and AI services they already rely on," said Eric Kessler, general manager of Amazon Braket at AWS.

The announcement comes amid rising government and industry spending on quantum computing, as countries and large technology groups compete to establish leadership in a field increasingly seen as strategically important. Investors and customers have been watching for signs that quantum systems can move from experimental devices to machines that perform useful tasks at meaningful scale.

QuEra says fault tolerance is the prerequisite for that shift because useful quantum applications depend not only on the number of logical qubits in a machine but also on how many operations can be completed before errors overwhelm the calculation. According to the company, Libra's projected logical error rate is 10−6.

Customer readiness

QuEra is also urging organisations to prepare for the arrival of fault-tolerant systems rather than wait for the hardware to appear. That message reflects a broader industry view that software, algorithms, and internal expertise may take years to build, especially for businesses seeking to test quantum methods against real operational problems.

"Waiting until 2028 to build a quantum strategy is a competitive risk," said Yuval Boger, chief commercial officer of QuEra.

"The algorithms that will harness fault-tolerant systems at this scale might not yet exist. Given that Libra will be available on the cloud in 2028 with a one-in-a-million error rate, the organisations that start co-developing now will be operational on day one, not catching up," Boger said.

Independent industry analysts also framed the move as a notable milestone for a sector that has often promised more than it has delivered. They pointed in particular to QuEra's emphasis on publishing technical progress and giving prospective users a clearer development path.

"QuEra's plan to deliver fault-tolerant systems in 2028 represents a significant inflection point for the quantum computing industry. QuEra's approach entails publishing every milestone, validating through peer review, and now offering concrete QC end-user engagement paths. This disciplined and visible strategy is what aspiring QC end users in HPC centres and related government programs want to see before committing substantial resources to an emerging technology," said Bob Sorensen, chief analyst for quantum computing at Hyperion Research.
