Not IonQ. Not Rigetti Computing. This Quantum Computing Stock Is the One I'd Buy and Hold Through 2030.

Quantum computers use quantum bits, or qubits, to tackle extraordinarily complex calculations that today's supercomputers struggle with.

Quantum computing is promising to transform critical industries such as drug discovery, materials science, cybersecurity, and financial services.

IonQ (IONQ +1.56%) and Rigetti Computing (RGTI -0.09%) are two of the most closely followed pure-play quantum computing stocks.

The catch is that neither company has built a consistently profitable business because commercially useful quantum computing remains years away.

IonQ and Rigetti have enormous financial risk On the surface, it might look like IonQ has made impressive progress in expanding its quantum computing platform.
