Amazon Braket has launched the general availability of IQM Quantum Computers (IQM)‘s latest quantum processing unit (QPU), named Emerald. This device is a 54-qubit superconducting QPU, featuring IQM’s Crystal 54 architecture. The Emerald QPU is designed to provide higher fidelity gates and full square lattice connectivity, and it is available through the Europe (Stockholm) Region on Amazon Braket.
The Emerald QPU utilizes superconducting transmon qubits arranged in a square lattice and interconnected via tunable couplers, supporting efficient mapping of quantum algorithms. The square lattice design natively supports surface-code error correction, positioning it for future fault-tolerant quantum computing applications. The device supports arbitrary X and Y rotations as native single-qubit gates and uses the CZ gate as its native two-qubit operation. Early characterization data indicates a median single-qubit gate fidelity of 99.93% and a median two-qubit gate fidelity of 99.5%. Emerald also supports Amazon Braket’s experimental dynamic circuits capability, enabling mid-circuit measurements and conditional quantum operations, and is accessible via the Braket SDK, Qiskit, Pennylane, and NVIDIA CUDA-Q.
Both IQM Emerald and IQM’s 20-qubit Garnet device are available for 19 hours a day on Amazon Braket, facilitating continuous experimentation globally. The addition of Emerald expands hardware options on Braket, which is relevant for developing quantum algorithms across domains like finance, energy, pharmaceuticals, and logistics. Its 54-qubit capacity is intended to enable the exploration of quantum algorithms requiring substantial qubit resources, such as preparing larger entangled states.
