AWS Reveals 54-Qubit Quantum Beast ‘Emerald’ on Braket to Power Next-Gen AI & Scientific Breakthroughs

Amazon Web Services has added IQM's Emerald, a 54‑qubit superconducting quantum processor, to its Amazon Braket quantum computing service, available now through the Europe (Stockholm) region.

Emerald, built with IQM’s Crystal 54 architecture, features a full square-lattice connectivity of superconducting transmon qubits and tunable couplers—enabling efficient execution of advanced quantum algorithms and supporting surface-code error correction for future error-resistant systems.

Performance benchmarks are impressive, with 99.93% median single-qubit gate fidelity and 99.5% across two-qubit gates.

The processor supports arbitrary X/Y rotations, native CZ gates, dynamic circuits, and mid-circuit measurements—paving the way for quantum error correction and advanced experimentation.

"Both IQM Emerald and Garnet are available 19 hours a day, enabling customers to run quantum workloads at their convenience regardless of time zone. The expanded availability windows from IQM enable continuous experimentation and development cycles for customers globally.

Customers can access these EU-based QPUs in the Europe (Stockholm) Region, meaning customers can meet European data residency requirements and work with cutting-edge hybrid quantum-classical computing capabilities all in one environment," AWS said in a blog post.

Researchers can run jobs on demand or reserve dedicated Braket Direct capacity. The device is accessible via popular SDKs and frameworks including Qiskit, Pennylane, CUDA-Q, and AWS Braket SDK.

Emerald joins the existing 20‑qubit Garnet processor, giving users versatile hardware options for real-world quantum research and applications in finance, energy, pharmaceuticals, logistics, and beyond.
