IonQ Quantum Computing Roadmap
A Tempo development system reached #AQ 64 on a 64-qubit computational register in September 2025; IonQ continues to list 100 qubits as Tempo's target. IonQ fabricated its first integrated 256-qubit Superion QPUs, trapped ions in prototype systems, pre-sold one system in Q1 2026, and targets customer deliveries in 2027.

Current system and qubit counts
Current system
Tempo development system
Physical qubits
64-qubit computational register demonstrated; IonQ continues to list 100 physical qubits as Tempo's product target.
Logical qubits
No current production logical-qubit count is stated in this record; 12 logical qubits is a 2026 company target.
IonQ's stated targets
Physical and logical qubit goals are labeled separately. A target date does not mean the milestone has been independently achieved.
