QuEra Unveils 2028 Roadmap for 256-Logical-Qubit “Libra” System and Expanded AWS Cloud Partnership

QuEra Computing and Amazon Web Services (AWS) have announced an expanded, multi-year strategic partnership focused on integrating fault-tolerant quantum computing into the cloud. The centerpiece of this collaboration is QuEra's upcoming 256-logical-qubit processor, codenamed Libra, which is scheduled for deployment on Amazon Braket by 2028. Classified as a “megaquop-class” system, Libra is engineered to execute approximately one million reliable logical quantum operations on hundreds of logical qubits, marking a significant step forward in operational quantum stability.

The system utilizes QuEra's neutral-atom (Rydberg) technology, which features optical tweezers for real-time atom manipulation and all-to-all connectivity. This architectural design allows for the implementation of high-rate, transversal error-correcting codes, significantly reducing the overhead of physical qubits required for logical operations. The development builds upon research conducted by QuEra in collaboration with Harvard University and MIT, with core concepts validated through multiple peer-reviewed studies in journals such as Nature and Physical Review Letters.

By hosting Libra natively on Amazon Braket, AWS aims to provide enterprises with seamless access to fault-tolerant quantum processing alongside classical HPC resources. The environment will support standard software frameworks, including Qiskit, PennyLane, CUDA-Q, and QuEra’s native Bloqade. Both companies emphasize that successful integration will require full-stack co-design, where algorithmic structures and error-correction schemes are tailored to the hardware's specific physical constraints.
