Rigetti Computing, Inc. - Common stock (RGTI)

Rigetti's 300-qubit target by mid-2028 is the milestone to watch, since it tests whether chiplet scaling can deliver the performance gains the company is betting on.

After IonQ's strong Q3 2026 results, D-Wave, QCi, and Rigetti posted mixed earnings with slower revenue, widening losses, and share price declines across quantum computing stocks.

Milestone chip results and roadmap updates headline a mixed quarter for the quantum computing pioneer.

Rigetti Computing (NASDAQ:RGTI) reported lower third-quarter revenue as the timing of system deliveries and contract milestones weighed on results, while management said it achieved a key performance target for its 108-qubit quantum computing system and set a roadmap for a larger machine. The compa

D-Wave Quantum and Rigetti are taking different approaches to developing quantum computers. Here's how their commercial progress and valuations stack up against IonQ's.

The quantum computing market is full of exciting investments, but not all of them will pan out.

Will Rigetti Computing hit its quantum milestones by 2029? Here is how to judge the stock's risk before it does.

The energy is coming out of the quantum computing theme.

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.
