Algorithmic Qubits & Standardization
IonQ bypasses direct logical qubit counting by pioneering the #AQ (Algorithmic Qubit) metric, which measures practical utility. Achieving #AQ 64 with Tempo theoretically matches the simulation capacity that would require 1 billion classical GPUs.
Derivation & Evidence
IonQ uses the #AQ (Algorithmic Qubit) metric to evaluate system utility. The successful demonstration of their 'Tempo' system achieved the #AQ 64 target early. IonQ's long-term roadmap targets 2 million physical qubits and 80,000 logical qubits by 2030 (a 25:1 ratio), demonstrating the exceptionally high conversion efficiency characteristic of their ion trap architecture.
