Qantum computers are special because can solve very big problems faster than regular computers. Many companies are working on this technology, and some of them have their stocks on the market.

In this article, we will look at two companies: Rigetti Computing (RGTI) and Quantum Computing Inc. (QUBT). We will see how they are doing, how strong their businesses are, and if their stocks are good to buy in 2025. Let’s dive in.

What Is Rigetti Computing (RGTI)?

Rigetti is a company that builds full quantum computing systems. This means they make both the parts (hardware) and the programs (software). They focus on something called superconducting qubits. 

These are tiny parts inside the computer that help do quantum calculations.

Rigetti builds its own chips in a factory they own, which helps them control how everything is made. Their newest machine is called Ankaa-3, and it has 84 qubits. 

That’s a big number for a quantum computer! Also, this system is very accurate. It has a 99.5% success rate when doing two-qubit operations.

How Is Rigetti Doing Financially?

Rigetti made about $10.8 million in revenue in 2024. That is not a huge amount, but the company is still growing. They are working with the government and other companies to grow faster.

Experts think Rigetti’s sales might grow by 34.5% in 2025. Even better, their earnings (profit) might grow by 44.4%.

They also have big goals. They want to create modular systems, which are easy to upgrade. By the end of 2025, they aim to have a system with over 100 qubits.

Is Rigetti’s Stock a Good Buy?

Rigetti’s stock is trading at a price-to-book (P/B) ratio of around 20.57. This number tells us the stock is expensive compared to the company’s assets. It means people expect the company to grow a lot. But it also means there’s some risk.

Big investment companies like Vanguard have been buying more shares of Rigetti. This shows that some investors believe in the company’s future.

Still, Rigetti had a drop in revenue in a recent quarter, and they are facing cost pressures. So, there are some challenges ahead.

What Is Quantum Computing Inc. (QUBT)?

QUBT is another company in the quantum space. It has recently done very well financially. In early 2025, it reported earnings of $0.13 per share. That’s a big improvement because it had losses before.

Its stock price went up by more than 3,000% in just one year! Even though it grew fast, it’s still a small company. But many investors are now watching it closely. The company is worth about $2.8 billion, which is a little less than Rigetti’s value.

QUBT Growth and Performance

For 2025, experts expect QUBT sales to grow by 34.1%. More impressively, its earnings might grow by 90.4%. That’s a very high number!

Compared to other quantum companies, QUBT is showing great performance. While it doesn't share as many details about its technology as Rigetti or IonQ, it is still considered a strong early-stage company.

Is QUBT a Good Stock to Buy?

QUBT is still new in the market. Because of that, it’s more risky. But it has shown that it can grow quickly. For investors who like high-reward stocks and are okay with some risk, QUBT could be exciting.

Comparing Rigetti (RGTI) and QUBT

Let’s see how the two companies compare:

Investment Outlook

Rigetti is more developed. It builds its own machines and has advanced technology. Investors who like strong systems and long-term plans may like Rigetti better.

QUBT is exciting because of its fast growth. If it continues to improve, it could become a strong player. But there is less known about its technology.

Both companies are working in a new market. Quantum computers are not widely used yet. Most of the big changes are expected after 2030. So, these stocks are like seeds. They may grow big one day, but investors need to be patient.

Conclusion

If you're looking for a strong, full-stack quantum company with real hardware, Rigetti might be the right choice. It has good backing and a solid growth plan.

If you’re interested in fast-moving, high-risk stocks that could deliver big returns, Quantum Computing Inc. (QUBT) is worth watching.

But remember: both companies are still in early stages. The quantum computing market is growing slowly now and will likely become big after 2030. These are long-term investments that may not show quick profits. Stay informed in Bitrue, and don’t invest more than you can afford to lose!

FAQ

What is the main difference between RGTI and QUBT?

RGTI builds both hardware and software for quantum computing and has a detailed tech roadmap. QUBT is more of a financial growth story with less technical detail available.

Is RGTI or QUBT better for 2025?

RGTI offers stability and technical depth. QUBT offers faster earnings growth but with more risk. The better pick depends on your investment style, safer growth vs. high risk/reward.

Why are quantum computing stocks risky?

The market is still new, with low commercial use today. Most profits are expected after 2030. Until then, companies may not earn much money.

What makes quantum computing special?

Quantum computers can solve problems regular computers can’t, like advanced simulations and big data tasks. They could help in medicine, science, and artificial intelligence.

What other quantum stocks are good to watch?

Besides Rigetti and QUBT, IonQ is another strong player. It uses trapped-ion qubits and shows better financial performance currently.
