AWS Deepens Strategic Collaboration with QuEra to Bring Fault-Tolerant Quantum Computing to Amazon Braket

AWS and QuEra will bring the first fault-tolerant quantum computers to the cloud, enabling scientifically relevant applications starting in 2028.

Since launching Amazon Braket in 2020, AWS has provided customers access to quantum computing hardware across multiple modalities, helping them explore quantum algorithms and prepare for the future of accelerated computing. Today, we are announcing an expanded strategic collaboration with QuEra Computing to bring Libra, the first fault-tolerant quantum computers capable of tackling scientifically relevant problems to Amazon Braket customers.

At AWS, we view quantum computing as a foundational compute modality. In the fullness of time, we envision quantum processors becoming a natural part of the AWS compute portfolio, alongside CPUs, GPUs, and AI/ML accelerators. Another tool in the toolbox our customers can rely on to accelerate production workloads and tackle problems out of reach for traditional compute options today.

QuEra has been a key quantum hardware provider to AWS since we started our quantum computing journey in 2019. In 2022, together we launched Aquila, a 256-qubit analog Rydberg device, built for scientific exploration. And over the past years, our customers in industry and academia have been pushing the boundaries of what we thought possible, driving innovation in quantum reservoir computing, high-energy physics simulations, and quantum algorithms for financial optimization.

Since we launched Aquila, neutral-atom quantum computing has matured rapidly. QuEra and affiliated academic partners at Harvard and MIT have demonstrated all the key ingredients for large-scale quantum error correction in a series of landmark experiments (e.g. 1. A fault-tolerant neutral-atom architecture for universal quantum computation, 2. Logical quantum processor based on reconfigurable atom arrays, 3. Experimental demonstration of logical magic state distillation, and 4. Continuous operation of a coherent 3,000-qubit system). Based on these results, we believe there is now a clear technical pathway to large-scale fault-tolerant quantum computers that coherently operate hundreds of logical qubits, and are capable of addressing scientifically relevant, and ultimately commercially relevant problems.

Today’s announcement builds on these results and takes our collaboration to the next level. Over the coming years, QuEra and AWS will be working together to bring fault-tolerant quantum computing to Amazon Braket, taking the next step in making quantum computing a foundational part of the AWS accelerated compute portfolio. By 2028, we will bring Libra, a Megaquop-scale device, capable of executing one million quantum operations over hundreds of logical qubits, to our customers, enabling first scientific applications in quantum chemistry, high-energy physics, and materials simulation that are beyond the reach of classical and Noisy Intermediate-Scale Quantum (NISQ) computers today.

We built Amazon Braket to make this possible. Braket brings fault-tolerant quantum computing directly to the AWS cloud, providing customers a single environment to develop, execute, and iterate on quantum applications alongside the classical infrastructure they already use. Through fully managed developer environments and support for leading quantum software frameworks including Qiskit, PennyLane, Bloqade, and CUDA-Q, Braket helps customers build, test, and optimize their applications for the underlying hardware. And because fault-tolerant workloads are inherently hybrid, Braket integrates natively with scalable HPC and AI resources on AWS, enabling customers to build end-to-end computational pipelines that move seamlessly between classical and quantum processors.

We are excited to see the scientific innovation our customers will drive with the first fault-tolerant quantum computers on Amazon Braket. The Megaquop-scale is not the finish line. It is the starting line. Together with QuEra, we aim to continue to expand these capabilities over the following years, to ultimately realize the full potential of quantum computing and unlock commercial applications across industries including pharmaceuticals, financial services, and advanced materials.

“This is a very special moment – for the first time, a dream of realizing useful, fault-tolerant quantum computers is in our direct line of sight. Designed to enable quantum computation at an unprecedented scale, these systems should realize truly unique applications. We are proud to significantly expand our collaboration with AWS to bring these unique capabilities to the broader community of scientific users”, said Prof. Mikhail Lukin, Chief Science Officer, QuEra Computing.

Getting ready for fault-tolerant quantum computing with AWS

The advances in neutral-atom (Rydberg) quantum computing over the past two years, have demonstrated two key advantages. First, Rydberg atoms scale naturally in the space dimension, and allow coherent operation of large qubit arrays (10,000 to 100,000+) within a single module without the need for interconnects between different modules. Second, atom arrays can be dynamically reconfigured without losing coherence by repositioning atoms using a technology called optical tweezers. Individual atoms are picked up using tightly focused laser beams and brought in close proximity to execute gate operations. This enables an effective all-to-all connectivity between qubits, which allows for more resource efficient fault-tolerant quantum algorithms (Constant-overhead fault-tolerant quantum computation with reconfigurable atom arrays, Low-overhead transversal fault tolerance for universal quantum computation, Towards Ultra-High-Rate Quantum Error Correction with Reconfigurable Atom Arrays ). Together, these capabilities provide a clear technical pathway to the first large-scale, fault-tolerant quantum processors.

We think that bringing the first quantum computers for computationally useful applications out of the lab and to our customers will be an important milestone on the path to commercial quantum computing. At the same time, we don’t believe quantum computing is a winner-take-all technology. Different modalities, such as ion-, superconducting-, and Rydberg-atom qubits, have distinct characteristics and limitations, and over time, we expect them to be progressively tailored towards applications that best suit their abilities. This mirrors what we are seeing in classical computing. If there is one thing we have learned over the past 20 years of building AWS, it is that there isn’t a single tool to rule them all. It is not the case in AI, it is not the case in databases, and it is not the case in compute, where an expanding set of architectures, from general-purpose CPUs to purpose-built accelerators, serve fundamentally different workloads. Customers want choice.

This is especially true in a technology like quantum computing, where we are at the beginning of the adoption curve and different architectures provide vastly different opportunities. At the AWS Center for Quantum Computing, for example, we are developing superconducting devices based on cat-qubit architecture, Ocelot — a technology we see as deeply complementary to Rydberg atoms. Where Rydberg atoms have advantages in scaling to larger qubit numbers and efficient qubit use through reconfigurability, superconducting qubits benefit from intrinsically fast clock cycles essential for deep-circuit applications and promise CMOS manufacturability economies of scale.

These complementary strengths also underscore an important reality: the first generation of fault-tolerant quantum applications will require extensive co-design across the full stack, from optimizing algorithmic structure and circuit decomposition to optimizing error correction schemes to the specific constraints of the underlying hardware. There is no off-the-shelf path to quantum advantage; early adopters will need to work hand-in-hand with hardware and software experts to tailor their applications to the device.

To support customers on this journey, we are working closely with QuEra and a growing group of software partners to help customers research, design, and validate their first fault-tolerant applications. These initial devices will have limited capacity.
