QuEra to Launch Fault-Tolerant Quantum Computer by 2028 — Expands Strategic Partnership with AWS Multi-Year

Boston, Massachusetts, USA — June 15, 2026

QuEra Computing (headquartered in Boston, Massachusetts, USA), a leading innovator in neutral-atom quantum computing, announced on June 15 local time the launch of its fault-tolerant quantum computer 'Libra,' set to begin operations in 2028. Additionally, the company announced a major expansion of its strategic partnership with Amazon Web Services (AWS) to make the system accessible via the cloud (see AWS's announcement here).

Fault-tolerant quantum computers are designed to perform complex calculations requiring longer processing times with high reliability, surpassing current quantum systems. This provides a pathway for enterprises, research institutions, and government agencies to develop workflows that solve problems such as molecular simulation, materials discovery, and optimization—areas where classical methods face scalability limits.

Libra, QuEra’s first fault-tolerant quantum computer and the first system under its expanded collaboration with AWS, is designed as a Megaquop-class system—capable of performing around one million logical quantum operations. This is critical because practical quantum programs depend not only on the number of logical qubits but also on the number of operations possible before errors fatally compromise the result. Libra is expected to achieve over 256 error-corrected logical qubits and a logical error rate of 10⁻⁶, enabling AWS customers to run early practical commercial and research workflows using fault-tolerant quantum computing by 2028.

Libra’s architecture has been validated through multiple peer-reviewed publications and builds upon QuEra’s proven track record in quantum computer development and deployment. QuEra has previously developed systems such as Aquila, a 256-physical-qubit system operating on Amazon Braket since 2022, and Gemini, a neutral-atom system with logical qubit capabilities co-located with Japan’s ABCI-Q supercomputer.

Andy Ory, CEO of QuEra Computing, stated:

"Fault-tolerant quantum computing is transitioning from research milestones to a roadmap for practical deployment. We have publicly executed this roadmap through expert-evaluated milestones and verified system evolution. With Libra, large-scale fault-tolerant quantum computing will be available on the cloud by 2028. This is an important first step, and as we will announce in our roadmap webinar this month, future versions will scale further. Leaders across industries should begin their preparations now so that talent, use cases, and workflows are ready when these systems go live."

Expanding the Strategic Partnership with AWS

QuEra and AWS are expanding their multi-year strategic partnership to deliver QuEra’s fault-tolerant quantum systems to AWS customers. Under this collaboration, Libra will be available on Braket starting in 2028. Braket, already integrated with HPC and AI/machine learning resources, provides an integrated environment for developing and running quantum programs alongside existing classical computing infrastructure for quantum-classical hybrid workflows. This partnership deepens a relationship that began in 2022 when Aquila became the first neutral-atom quantum computer available on Braket.

Eric Kessler, General Manager of Amazon Braket at AWS, stated:

"We believe fault-tolerant quantum computing will be the foundation for customers to solve their most challenging computational problems on AWS. QuEra’s technology has demonstrated a clear path toward that future. By delivering this capability to customers through Amazon Braket, they will be able to combine QuEra’s fault-tolerant quantum processors with the large-scale AWS HPC and AI services they already use."

Building on Proven Foundations

QuEra pioneered quantum error correction in 2023 and has continued to advance fault-tolerant technologies. Since fault tolerance is a prerequisite for commercially viable quantum computing, QuEra has remained dedicated to its realization. All components of the Libra architecture have been validated through peer-reviewed research.

QuEra’s research team and the founders’ labs (Harvard University and MIT) have published eight peer-reviewed papers in Nature and Physical Review Letters, demonstrating the following foundational technologies:

- Logical qubits, the fundamental building blocks of error-corrected quantum computing - Techniques to reduce error rates below threshold, enabling error reduction as the system scales - Transversal logical operations and fast, low-overhead gates between qubits - High-speed decoding for large-scale real-time error correction - Continuous operation of thousands of qubits through continuous atom replenishment - Resource-efficient error-correcting codes that reduce the physical qubit cost per logical qubit

Towards 2028, QuEra will continue to evolve its fault-tolerant systems. Based on these advanced designs, the company will accelerate roadmap execution and provide strategic partners early access to fault-tolerant computing environments ahead of broad public availability.

Preparing for the Era of Fault Tolerance

Yuval Boger, Chief Commercial Officer (CCO) of QuEra, stated:

"Not planning a quantum computing utilization strategy by 2028 poses a competitive business risk. Algorithms capable of leveraging quantum systems at this scale may not yet exist. However, by starting co-development now, organizations can be ready to utilize Libra from day one when it launches on the cloud in 2028 with a one-in-a-million error rate, avoiding the need to play catch-up."

Bob Sorensen, Chief Analyst for Quantum Computing at Hyperion Research, stated:

"QuEra’s plan to deliver a fault-tolerant quantum system by 2028 is a major inflection point for the quantum computing industry. In addition to publicly disclosing all milestones and undergoing expert validation, QuEra has now presented a concrete path toward building relationships with end users of quantum computing. End users in HPC centers and related government programs demand such disciplined, clear strategies before making significant investments in new technologies."
