IONQ IncIonQ holds world record for two-qubit gate fidelity at 99.99%, higher than Alphabet's 99.88%.
Alphabet and IonQ are pursuing distinct quantum computing technologies, with Alphabet using superconducting qubits and IonQ employing trapped ions. IonQ holds a world record for two-qubit gate fidelity at 99.99%, compared to Alphabet's 99.88%, though Alphabet's approach offers faster speeds. Alphabet benefits from its core Google business to self-fund quantum research, while IonQ relies on research contracts and single-system sales. The analysis suggests Alphabet is a more conservative investment, while IonQ represents a higher-risk, higher-reward opportunity.
