Rigetti Computing, Inc. - Common stock (RGTI)

Meaningful revenue from quantum computers could be many years away.

These pure plays are making important progress toward their goals.

IonQ's revenue rose 287% and Rigetti's 185% last quarter, but both carry steep valuations. Here's how the two compare on risk and fit.

D-Wave grew revenue 178% in 2025 while Rigetti's fell 34%, yet both burn cash at similar rates, a stark contrast that reshapes the investment calculus.

Be cautious before rushing into pure-play quantum computing.

Rigetti Computing's accuracy is a major issue.

Teradyne, Grail, Kratos Defense, FormFactor and Fabrinet have pulled back despite strong growth, setting up potential entry points in robotics, quantum and AI.

Both companies are experiencing sales growth but also substantial losses.

IonQ and Rigetti Computing are two popular pure-play quantum computing stocks.

Quantinuum hit 99.9995% logical fidelity on its Helios system and holds $2.1 billion in cash, even as shares trade near 52-week lows and Morgan Stanley issues an Overweight rating.

The people who know Wall Street’s pure-play quantum computing companies best are sending all the wrong signals.

Three of these companies are pure plays burning cash in pursuit of a market that barely exists yet. For the other three, quantum computing is a sideshow -- so far.

BigBear.ai is showing early signs of a turnaround with new contract wins and improving margins. Rigetti has advancing quantum hardware but limited commercial revenue and a long road to scale.

Big risks can often yield big rewards.

IonQ and Rigetti get all the quantum computing headlines, but these three stocks might be better positioned to outperform this fall.

Rigetti Computing is making inroads in the quantum computing landscape with big tech.

There are good reasons not to jump on board with quantum computing stocks just yet.

D-Wave is growing revenue at nearly 180% while Rigetti trades at a lower valuation, but both burn cash heavily and face unproven commercial roadmaps.

These ETFs take the guesswork out of finding the best quantum computing stock.

Both pure plays just received additional government funding and have a few customers.

Both companies are losing money and asking investors to be patient, but one is at least growing its revenue while the other has seen sales decline.

IonQ, D-Wave, and Rigetti are taking quantum computing from the experimental stage to the commercial stage, and early investors could reap outsize rewards.
