Qubit count (physical_qubit_count)25 qubitsvendor claim
Vendor claim
- Method
- VENDOR_UNSPECIFIED
- Notes
- Corroborated by Azure Quantum docs (25 qubits, ionq.qpu.aria-1). Earlier configuration had 21 physical qubits per IonQ's 'Aria: Practical Performance' whitepaper (page shows Jan 8, 2025 but describes the launch-era system with #AQ 20).

Algorithmic qubits (#AQ) (algorithmic_qubits_AQ)25 #AQvendor claim
Vendor claim
- Method
- IonQ algorithmic-qubit benchmark suite (application-based, derived from QED-C protocols)
- Notes
- #AQ history: 20 in the 'Practical Performance' whitepaper; 23 at Azure Quantum launch (IonQ press release, Aug 16, 2022, businesswire.com/news/home/20220816005315/en). #AQ is IonQ's application benchmark, distinct from physical qubit count (25).

Two-qubit gate quality (two_qubit_gate_fidelity)99.4% (stated as 0.6% 2Q gate error) %sources conflict
Conflicting sources
- Method
- vendor spec page attributes 2Q gate to concatenated Molmer-Sorensen gate technique; benchmarking method not stated
- Aggregation
- not stated on spec page
- Notes
- Two live vendor-sourced pages disagree: current ionq.com spec page shows 0.6% 2Q error (=99.4%), while Azure docs and the IonQ practical-performance whitepaper show 99.6% average (0.4% error).
