IonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge?

Key Points IonQ still appears to have the accuracy edge, while its connectivity and early progress on error-correction strengthen its advantage. Rigetti Computing's 108-qubit system is much faster, but its larger systems showed lower accuracy. The winners of the quantum race will be decided by how well their technologies perform at much larger scales. 10 stocks we like better than IonQ › IonQ (NYSE: IONQ) and Rigetti Computing (NASDAQ: RGTI) are taking entirely different technological routes in their efforts to build useful quantum computers. IonQ uses trapped-ion technology, where individual charged atoms held in place by precise electromagnetic fields serve as qubits, the basic units of information in any quantum computer.
