Hardware Deep Dive

IQM Emerald is IQM's 54-qubit superconducting processor, launched on AWS Braket in July 2025. It is built on IQM's Crystal 54 architecture -- a square lattice of transmon qubits interconnected by tunable couplers, scaling up the same design principles proven on the 20-qubit Garnet. The 54-qubit count is not arbitrary: the square lattice geometry is the standard layout assumed for surface-code quantum error correction, meaning Emerald's topology maps directly to the most widely studied fault-tolerant computing scheme. Emerald is available 19 hours per day and is hosted within the EU in one of IQM's European quantum data centres.

Common Provider Questions

What does "surface-code ready" actually mean?

Surface codes are a family of quantum error correction codes that protect logical qubits from noise by distributing information across many physical qubits arranged in a 2D grid. The correction protocol only requires measurements between nearest-neighbour qubits, which maps exactly to a square lattice topology. Emerald's Crystal 54 layout is therefore geometrically compatible with surface-code experiments without any qubit routing overhead for the syndrome measurements. This does not mean Emerald runs fault-tolerant circuits today -- the qubit count and gate fidelity are not yet at the threshold needed for useful fault tolerance -- but the hardware is purpose-built to study and prototype these techniques.

How does Emerald compare to Garnet?

Emerald scales the same tunable-coupler architecture from Garnet's 20 qubits to 54, using the Crystal 54 design. Early characterisation data shows Emerald's single-qubit fidelity (99.93%) and two-qubit fidelity (99.5%) are comparable to Garnet (99.92% / 99.51%), demonstrating that IQM has maintained gate quality while more than doubling the qubit count. Emerald is the larger device for workloads that need more qubits or deeper circuits, while Garnet remains available for smaller experiments at the same fidelity level and in the same AWS region.

Does Emerald support dynamic circuits?

Yes. Like Garnet, Emerald supports mid-circuit measurements and feed-forward operations as an experimental capability on AWS Braket. Circuits can measure qubits mid-execution and apply subsequent gates conditioned on those outcomes. AWS documentation notes Emerald has 4 groups of qubits (versus Garnet's 2), reflecting the larger lattice partition for mid-circuit measurement operations. This is enabled via experimental_capabilities="ALL" in the Braket SDK.

Why does EU hosting matter for Emerald?

Both IQM Emerald and Garnet are physically hosted within the European Union and routed through the AWS eu-north-1 (Stockholm) region. This means circuit data, job results, and metadata remain within EU jurisdiction throughout the entire workflow. For research institutions, public sector entities, or companies subject to GDPR or national data sovereignty requirements, this is a practical requirement that many US-hosted QPUs cannot currently meet.
