IonQ Is Bringing a 100-Qubit System to South Korea. Should You Buy IONQ Stock for 2026?

IonQ (IONQ), the largest pure-play quantum computing company in terms of market capitalization and revenue, has deepened its relationship with the Korea Institute of Science and Technology Information (KISTI). As part of this partnership, the company will now deliver its Tempo 100 quantum system to support the institution's hybrid quantum-classical research endeavors. 

The Tempo 100 is IonQ's current flagship commercial quantum computer, defined by Algorithmic Qubits (AQ) instead of raw qubit count. AQ is IonQ’s performance metric that reflects how many usable, low-error, fully connected qubits a customer can actually run algorithms on. In contrast, 100 refers to approximately 100 high-quality, error-corrected-ready qubits, accounting for gate fidelity, coherence time, and connectivity.
