IQM Emerald
IQM Emerald is a superconducting circuits quantum computer operated by IQM Quantum Computers in Finland. It has 54 physical qubits. It ranks 25 of 43 superconducting machines in this table by physical qubit count. 14 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Emerald 54-qubit QPU
IQM's 54-qubit device, listed on Amazon Braket alongside the 20-qubit Garnet and described there as a square-lattice superconducting transmon device. The sources used give no launch date, fidelity figures or physical location, so those fields are blank.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Processor | IQM Crystal 54 QPU | Vendor reported | AWS says Emerald features IQM Crystal 54 architecture; IQM calls Crystal 54 its flagship device on Resonance. | aws.amazon.comiqm.tech |
| Qubit type | transmon | Independent | AWS docs and the DLR paper both describe Emerald as superconducting transmon-based. | docs.aws.amazon.comarxiv.org |
| Topology | square lattice with tunable couplers | Independent | Both describe a 54-qubit square lattice with tunable couplers. | aws.amazon.comarxiv.org |
| Max connectivity | 4 | Vendor reported | IQM describes the Crystal square lattice as having four nearest neighbors per qubit; family-wide statement, bulk qubits only. | iqm.tech |
| Couplers | 85 | Independent | A Saint Louis University paper (dated 2026-09-01) reports 85 calibrated two-qubit couplings in a Braket calibration snapshot; physical coupler count may be higher. | arxiv.org |
| Native gates | PRX (arbitrary X and Y rotation) and CZ | Independent | AWS lists cz and prx for IQM devices and the launch blog names X/Y rotations plus CZ; the DLR paper states PRX and CZ. | docs.aws.amazon.comarxiv.org |
| Cooling and environment | dilution refrigerator | Vendor reported | IQM technology page says its superconducting circuits are cooled with dilution refrigerators; family-wide statement, not specific to Emerald. | iqm.tech |
| Power draw | 26 kW | Vendor reported | IQM Radiance 54 datasheet typical mean total electrical power for the on-premises system; Emerald itself is IQM-hosted. | iqm.tech |
| Fabrication | IQM's own fab in Espoo, Finland | Vendor reported | IQM whitepaper says IQM QPUs are made in its dedicated Espoo facility; family-wide statement from the Garnet document. | arxiv.org |
| Software | Braket SDK, Qiskit, PennyLane, CUDA-Q (Braket); Qiskit, Cirq, CUDA-Q, TKET, Qrisp (Resonance) | Vendor reported | Frameworks named by AWS for Emerald on Braket and by IQM for its Resonance cloud. | aws.amazon.comiqm.tech |
| Cloud platforms | Amazon Braket (Europe Stockholm region); IQM Resonance | Vendor reported | AWS announced general availability on 2025-07-22; IQM added Emerald to Resonance on 2025-08-05. | aws.amazon.comiqm.tech |
| Access and pricing | Cloud queue on Amazon Braket: $0.30 per task + $0.00160 per shot, or $4,000 per hour reserved | Vendor reported | Prices from the AWS Braket pricing page checked 2026-10-09; Braket Direct reservations and Hybrid Jobs priority access also exist. | aws.amazon.comaws.amazon.com |
| Predecessor | IQM Garnet | Vendor reported | IQM names Garnet (Crystal 20) as the predecessor, with almost triple the qubits. | iqm.tech |
| Roadmap | Halocene 150-qubit error-correction system by end 2026, 1,000+ qubit models later, fault tolerance by 2030 | Vendor reported | IQM Halocene announcement of 2025-11-13 (press release reprint); roadmap page checked 2026-10-09; this is the IQM Crystal line roadmap, not an Emerald-specific upgrade. | thequantuminsider.comiqm.tech |
