IonQ (NYSE: IONQ) Holds Technology Edge Over Rigetti (NASDAQ: RGTI) In Pure-Play Quantum Computing Race

IonQ (NYSE: IONQ) and Rigetti Computing (NASDAQ: RGTI) represent two of the most closely watched pure-play quantum computing stocks available to investors today.

Both companies are unprofitable and carry significant risk, but examining their underlying technologies offers a clearer picture of which firm has a stronger path forward.

The fundamental difference between these two companies lies in how they approach the core challenge of quantum computing at the hardware level.

Rigetti relies on superconducting technology, a method that requires cooling particles in a chamber to near absolute zero temperatures before they can be used for quantum computation.

This superconducting approach is also favored by many established legacy technology giants, meaning Rigetti is competing directly against far larger and better-resourced competitors.

IonQ takes a distinctly different route, using lasers to pinpoint and cool individual particles before trapping them in an ion trap described as similar to a maze.

This trapped-ion method gives IonQ a significant accuracy advantage over superconducting alternatives, though the trade-off is that IonQ’s approach is considerably slower in terms of gate speeds.

Rigetti’s superconducting technology, by contrast, operates with faster gate speeds, which is the one area where it holds a meaningful technical edge over its rival.
