During the third-quarter earnings call, Rigetti Computing RGTIacknowledged that advancing to the next stage of quantum performance will eventually require more sophisticated chip manufacturing capabilities.

Rigetti Computing boasts an interesting picks-and-shovels strategy. But commercially viable quantum devices remain years away. For now, companies like Rigetti rely more on hype than fundamentals. It's generally not a good idea to buy stocks that have recently rallied based on hype.

This is allowing IBM to attack quantum computing with two very different chips.

D-Wave, IonQ, and Rigetti are rising quantum computing stars with different approaches. Wall Street remains bullish about all three stocks after their recent declines. Other quantum computing stocks also enjoy Wall Street's favor, including Quantum ...

Quantum computing stocks like Rigetti surged on hype but are now plunging. We examine whether the quantum boom is over and if RGTI is still worth buying amid major risks.

Overview: Quantum computing is moving steadily from research into early commercial use across industries.Pure-play firms like Rigetti Computing offer high growt

Rigetti Computing RGTI competitive positioning is built around its vertically integrated superconducting quantum computing stack, spanning in-house chip design, fabrication, packaging and

Two of those early movers are IonQ ( IONQ +3.12%) and Rigetti Computing ( RGTI +1.91%). Both of these quantum stocks are volatile and richly valued relative to their near-term growth; however, which one offers more upside potential for long-term investors?

SEEQC, which traces its lineage back to IBM, is building the world’s quantum computers. They might prove critical in the global race for quantum supremacy.
