AQT LRZ Ion-Trap System
AQT LRZ Ion-Trap System is a trapped ions quantum computer operated by LRZ in Germany. It has 20 physical qubits. It ranks 9 of 15 trapped ion machines in this table by physical qubit count. 6 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as LRZ AQT 20-qubit system
20-qubit AQT system procured by LRZ and Munich Quantum Valley with about 9.8 million euros of Bavarian funding, delivered in December 2023 and operational for early users by October 2024. LRZ states it plans to integrate it as an accelerator in its supercomputer environment, but no specific supercomputer is named, so no HPC link is recorded. No fidelity or quantum volume figures are published on these pages.
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 | Trapped ions, laser-controlled | Vendor reported | LRZ describes electrically charged atoms whose quantum states are controlled by laser beams; the ion species is not stated. | lrz.deaqt.eu |
| Topology | All-to-all: a laser can address arbitrary pairs of the 20 qubits | Independent | LRZ press release of 2024-09-25 describes full connectivity of the 20-qubit register. | lrz.de |
| Cooling and environment | No extensive cooling or power infrastructure needed | Independent | LRZ states this in general terms and gives no temperature; the system was installed in a computer room with dust filtering and vibration adjustments. | lrz.de |
| Software | Munich Quantum Software Stack (MQSS) | Independent | LRZ says the AQT device is a key target for developing MQSS, built by Munich Quantum Valley with LRZ and TUM. | lrz.de |
| Access and pricing | On-premises at LRZ; early user program for Munich Quantum Valley researchers from October 2024 | Independent | Procured by LRZ and Munich Quantum Valley; no price published. | lrz.deaqt.eu |
| Roadmap | LRZ plans to integrate it as an accelerator in its supercomputer environment | Independent | Stated 2024-09-25; no specific supercomputer is named. | lrz.de |
