AWS and QuEra Partner to Bring Fault-Tolerant Quantum Computers to the Cloud by 2028
When Amazon Web Services and QuEra Computing announced their partnership, the quantum‑computing world received a clear signal that fault‑tolerant machines are moving from theory to the cloud.
The two companies have struck a multi‑year agreement to deliver a quantum system with built‑in error‑correction to AWS’s cloud platform within the next two years, followed by a next‑generation machine called Libra in 2028. The core of the effort is error‑control technology. Qubits—the basic units of quantum information—are notoriously fragile. Tiny vibrations or stray electromagnetic fields can flip their states, rendering a calculation wrong. Fault‑tolerant systems that automatically detect and correct such errors are widely regarded as essential for practical quantum computing.
QuEra’s approach is built on neutral atoms excited to Rydberg states. Precision laser beams, acting as optical tweezers, manipulate these atoms with millimeter‑scale accuracy. The startup claims it has already demonstrated control of thousands of qubits in a single module, a milestone that positions its platform as a scalable alternative to the superconducting‑circuit systems used by IBM and Google.
Founded in 2018 by researchers from Harvard University and the Massachusetts Institute of Technology, QuEra has pursued a different path to scalability and stability. Its chief scientific officer, Mikhail Lukin, has said that recent progress makes a fault‑tolerant quantum computer a realistic goal.
AWS has a long history of working with QuEra. In 2022 the startup supplied its 256‑qubit analog quantum computer, Aquila, to AWS Braket, a managed service that lets researchers run quantum algorithms on a variety of back‑ends from a single cloud interface. Braket supports hybrid workflows that combine classical AWS resources with quantum processors.
The Libra system is described by AWS as a MegaQuOp‑class machine capable of more than one million quantum operations per second and of supporting hundreds of error‑corrected logical qubits. If achieved, the performance would surpass current supercomputers in domains such as materials science, quantum chemistry, and high‑energy physics.
AWS has stated that it does not expect the quantum industry to converge on a single hardware architecture. The company is pursuing cat‑qubit technology at its Center for Quantum Computing while also partnering with QuEra on neutral atoms. This dual‑track strategy reflects the view that different quantum systems may be best suited to different application areas.
Industry analysts note that the partnership aligns with AWS’s broader quantum roadmap, which includes Amazon Braket, the AWS Quantum Solutions Lab, and the AWS Center for Quantum Computing. AWS has also announced a Quantum Embark program to help customers prepare for quantum workloads.
The 2028 target is presented as a starting point. Both companies plan to refine Libra’s error‑correction capabilities and expand its use to fields such as drug design and financial modeling.
As of now, the collaboration has not yet produced a commercial product. The next milestone is the delivery of a quantum system with error‑correction to the AWS cloud within two years, followed by the Libra release in 2028. The partnership represents a significant step toward making fault‑tolerant quantum computing available to a broader research and commercial community.
The announcement underscores AWS’s commitment to a platform strategy that accommodates multiple quantum architectures, rather than betting on a single technology path. The outcome of this partnership will likely influence the direction of quantum hardware development and cloud‑based quantum services in the coming years.
