IonQ Tempo
IonQ Tempo is IonQ's next-generation trapped-ion system following Forte, designed to push algorithmic qubit counts higher while maintaining the high gate fidelity and all-to-all connectivity that distinguishes trapped-ion architectures from superconducting alternatives.
Qubit Count
36
Qubit Type
Trapped-ion (ytterbium ions)
Architecture
Linear ion trap with all-to-all connectivity
Released
2025
Gate Error (2Q)
~0.05–0.1% per two-qubit gate
Coherence Time
T₂ > 1 second
Operating Temp
Room temperature (ion trap operates in vacuum)
Cloud Access
Yes — AWS Braket, Azure Quantum, IonQ direct access
Company
IonQ
Connectivity
All-to-all — any qubit can directly interact with any other qubit
Key Features
- Improved algorithmic qubit count over the previous Forte generation
- Maintains all-to-all connectivity, simplifying circuit compilation
- Designed with enterprise and government deployment in mind
- Available through multiple major cloud platforms
Limitations
- Still fewer raw qubits than leading superconducting processors
- Gate operation speed remains slower than superconducting alternatives
Technical Notes
IonQ continues to emphasize 'algorithmic qubits' as its primary performance metric rather than raw physical qubit count, arguing that high-fidelity, fully-connected qubits at modest scale outperform much larger, noisier processors for real algorithm execution.
