Investing.com -- Amazon (NASDAQ:AMZN) Braket has expanded its quantum computing hardware offerings with the general availability of IQM’s new 54-qubit superconducting quantum processing unit (QPU) called Emerald. The new processor joins IQM’s 20-qubit Garnet device on the Amazon Braket platform, with both quantum processors accessible through the Europe (Stockholm) Region. This addition gives customers more options for selecting appropriate quantum hardware for their specific research and algorithm requirements. Emerald features IQM’s Crystal 54 architecture using superconducting transmon qubits arranged in a square lattice with tunable couplers connecting them. This high-connectivity design enables efficient algorithm mapping and natively supports surface-code error correction for future fault-tolerant quantum computing. Early performance data shows the processor achieving 99.93% median single-qubit gate fidelity and 99.5% median two-qubit gate fidelity. The device supports arbitrary X and Y rotations as native single-qubit gates and uses the CZ gate as its native two-qubit operation. Both IQM quantum processors are available 19 hours daily, allowing customers worldwide to run quantum workloads regardless of time zone. The EU-based QPUs help customers meet European data residency requirements while working with hybrid quantum-classical computing capabilities. Amazon Braket provides a unified programming interface for accessing quantum hardware, allowing customers to build and run quantum programs using the Braket SDK or other frameworks like Qiskit, Pennylane, and NVIDIA (NASDAQ:NVDA) CUDA-Q. Emerald’s 54-qubit capacity enables exploration of quantum algorithms requiring substantial qubit resources, including larger entangled states and more complex quantum circuits. The processor also supports Amazon Braket’s experimental dynamic circuits capability, which allows mid-circuit qubit measurements and conditional operations. Following the announcement, shares of Quantum Computing Inc (NASDAQ:QUBT) fell 5.5% and D Wave Quantum Inc (NYSE:QBTS) pared gains to 2.3%, and Amazon stock gained 1%.
