IQM Garnet accessible through Amazon Braket

IQM Garnet is a high-fidelity 20-qubit quantum processing unit (QPU) based on superconducting transmon qubits. The qubits are arranged in a square lattice and connected by tunable couplers. The system is calibrated to support arbitrary X and Y rotations as the native single-qubit gate and CZ as the native two-qubit gate. IQM Garnet contains 20 computational transmon qubits and 30 tunable coupler qubits and a square lattice topology enabling high connectivity.

Up-to-date characterization data can be found on IQM Garnet’s device details page in the Amazon Braket console. More information on the latest IQM Garnet benchmarking results can also be found here.

IQM’s Superconducting Quantum Processors

Among many physical platforms, superconducting quantum hardware excels both in scalability and control, making it a strong contender for fault-tolerant quantum computing. For Noisy Intermediate Scale Quantum applications, the unique IQM approach enables our users to experience the best quality and accuracy.

Tunable couplers

Quantum algorithms rely on high-quality two-qubit gates for computational advantage, but stray coupling ("crosstalk") can degrade gate quality. IQM's quantum computers address this with tunable coupler technology based on transmons, enabling full idling of interaction, minimizing errors and enabling fast gates (20 ns – 40 ns). Although tunable couplers increase the effective qubit count overhead, IQM has successfully leveraged this technology to attain its exceptional device quality.


We are committed to delivering best-in-class fidelity with our quantum systems to enable usability. With IQM Garnet, we achieve median 1-qubit gate fidelity of 99.92% and median 2-qubit gate fidelity of 99.51%, and you can access the full range of qubits for your quantum research. We achieve this through high-quality qubits with industry-leading fidelities, enabling us to execute many steps of quantum circuits and to fully entangle qubits. This makes our superconducting qubits highly useful for quantum algorithms.

Execution Time

IQM's fast gate speeds and high-quality qubits allow for thousands of gate operations during the lifetime of our qubits. That removes a bottleneck in the effective integration of our quantum systems into hybrid environments, making them suited to execute variational algorithms such as quantum machine learning.

Use Cases with IQM

With IQM’s high-fidelity data qubits, we anticipate significant progress in using quantum algorithms for optimization, simulation, and machine learning across various fields such as life sciences, chemistry, and other industrial applications.
