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

IonQ (IONQ -1.20%) and Rigetti Computing (RGTI -1.18%) are taking entirely different technological routes in their efforts to build useful quantum computers.

Rigetti Computing uses superconducting qubits, which are tiny electrical circuits cooled to extremely low temperatures.

IonQ's quantum computing technology That narrower accuracy gap could prove crucial when quantum calculations become more complex.

Rigetti Computing's quantum computing technology Rigetti's much faster quantum computing operations could give it a major advantage if it can improve accuracy while building larger systems.

Rigetti Computing could narrow the gap if it improves accuracy while preserving its existing advantages in speed and scalability.
