AQT IBEX Q1
AQT IBEX Q1 is a trapped ions quantum computer operated by AQT in Austria. It has 12 physical qubits. It ranks 13 of 15 trapped ion machines in this table by physical qubit count. 9 sourced specs are in the spec sheet. 3 published benchmark or milestone records are listed below, each marked by who measured it.
Also known as IBEX-Q1
AQT's 12-qubit cloud system, operated from AQT's Innsbruck headquarters and listed as a device on Amazon Braket (eu-north-1). AQT reports a quantum volume of 128. The AQT page and the Open Quantum listing differ slightly on two-qubit fidelity (98.7 versus about 98.85 percent). Launch date not stated in the pages consulted.
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 |
|---|---|---|---|---|
| Qubit type | 40Ca+ ion crystal in a radio-frequency trap | Independent | AWS Braket documentation describes the QPU as a crystal of 40Ca+ ions in a macroscopic RF trap; Quantum Computing Report also says calcium-40. | docs.aws.amazon.comquantumcomputingreport.com |
| Topology | All-to-all, 12 fully connected qubits | Vendor reported | AQT lists 12 fully connected qubits; the AWS announcement states all-to-all connectivity with no SWAP gates needed (checked 2026-10). | aqt.euaws.amazon.com |
| Native gates | RZ, R, RXX (Braket names: rz, prx, xx) | Vendor reported | AQT lists basis gates RZ, R, RXX; AWS documents native gates prx, xx, rz for verbatim compilation, mapping RXX to the Molmer-Sorensen xx gate. | aqt.eudocs.aws.amazon.com |
| Cooling and environment | Room-temperature operation, ion trap in an ultra-high vacuum chamber | Vendor reported | AQT states operation at 22 +/- 1.5 C and under 60 percent humidity; AWS documentation states the trap sits in an ultra-high vacuum chamber. | aqt.eudocs.aws.amazon.com |
| Power draw | 2 kW | Vendor reported | AQT states consumption below 2 kW via a single power plug, so 2 is an upper bound, not a measured draw. | aqt.euquantumcomputingreport.com |
| Software | Qiskit, Cirq, Pytket on ARNICA; Qiskit, Braket SDK, PennyLane, CUDA-Q via cloud partners | Vendor reported | AQT cloud page lists SDK support per access route (ARNICA, Scaleway, AWS); lists are for AQT cloud access generally, checked 2026-10. | aqt.eu |
| Cloud platforms | AQT ARNICA; Amazon Braket (eu-north-1); Scaleway; Horizon Quantum; Classiq; qBraid; Open Quantum | Vendor reported | AQT cloud page lists these access routes; the AWS Braket device table independently lists IBEX-Q1 as arn:aws:braket:eu-north-1::device/qpu/aqt/Ibex-Q1. | aqt.eudocs.aws.amazon.com |
| Access and pricing | Cloud: ARNICA pay-as-you-go at 0.03 EUR per circuit plus 0.02 EUR per shot, or exclusive reservation at 3500 EUR per hour | Vendor reported | Published AQT pricing plan page (checked 2026-10); pay-as-you-go runs in fixed weekly windows Mon, Tue, Wed and Fri UTC, exclusive use is by reservation; Braket and Scaleway have their own pricing. | aqt.eu |
| Successor | AQT LYNX | Vendor reported | AQT describes the LYNX series as an evolution of the IBEX series with a 256x higher quantum volume (May 2026). | aqt.euaqt.eu |
Published benchmark figures
These are numbers the builder or a paper reports for this machine, not results from a common test. The basis column says who measured them. What the metrics mean and why they are not comparable across technologies.
| Metric | Value | Measured | Basis | Note | Source |
|---|---|---|---|---|---|
| Quantum volume | 128 | 2026-10 | Vendor reported | QV 2^7 as stated on AQT IBEX Q1 product page | aqt.euopenquantum.com |
| Single-qubit gate fidelity | 99.97% | 2026-10 | Vendor reported | 99.97 +/- 0.01 percent per AQT product page | aqt.euopenquantum.com |
| Two-qubit gate fidelity | 98.7% | 2026-10 | Vendor reported | 98.7 +/- 0.3 percent per AQT product page; Open Quantum lists about 98.85 percent | aqt.eu |
