IonQ has achieved 99.99% 2-qubit gate fidelity, making it the leader in that metric among trapped-ion quantum computing companies, while Quantinuum has recorded 99.9975% 1-qubit gate fidelity and 99.92% 2-qubit gate fidelity. IonQ's accuracy milestone is attributed to its acquisition of Oxford Ionics and its proprietary Electronic Qubit Control technology, which uses microwave antennas built directly on chips to improve stability and shrink system size. Quantinuum has avoided embedding microwave antennas, arguing that laser-based gates are faster and more power-efficient, and it is also known for its robust software stack including the open-source language Guppy, the TKET development kit, and the Nexus cloud operating system. Both companies have similar market capitalizations around $20 billion, and while IonQ is favored for its accuracy lead and vertical integration efforts, the article suggests investors could take small speculative positions in both stocks.

Quantinuum Inc. Class A Common StockQuantinuum's 2-qubit gate fidelity (99.92%) is lower than IonQ's, and its laser-based approach is contrasted as less accurate, though it has strengths in software.
