Quantum Computing Stocks Are Booming! Here’s Why Investors Are Paying Attention

The race to develop practical quantum computing is heating up, and investors are keeping a close eye on the companies leading this revolutionary technology. With breakthroughs in processing power and algorithm efficiency, the quantum computing industry is drawing increased attention from Wall Street.

While the sector is still in its early stages, several key players are making significant strides toward building real-world applications. Here’s a look at the top quantum computing stocks investors should be watching right now.

Rigetti Computing (NASDAQ: RGTI)

Founded in 2013, Rigetti Computing is one of the few publicly traded pure-play quantum computing companies. Specializing in superconducting qubit technology, Rigetti recently launched an 84-qubit single-chip quantum processor, a major step toward scaling up its systems.

While its stock has seen high volatility, Rigetti remains a major name in the space, working with government agencies and private enterprises to advance quantum applications.

D-Wave Quantum (NYSE: QBTS)

D-Wave is another big name in the quantum computing industry, focusing on quantum annealing technology—a different approach from traditional gate-based quantum systems.

Recently, D-Wave announced a groundbreaking achievement, claiming that its quantum system outperformed a leading classical supercomputer in solving complex simulations. This news sent D-Wave’s stock soaring more than 11% as investors reacted to the breakthrough.

IonQ (NYSE: IONQ)

IonQ is developing trapped-ion quantum computers, which some experts believe offer greater stability and accuracy compared to other quantum technologies.

Following D-Wave’s recent announcement, IonQ’s stock also saw a 16% jump, reflecting renewed investor interest in the sector. The company has formed partnerships with Google, Amazon, and Microsoft, positioning itself as a serious competitor in the commercial quantum race.

Microsoft Corporation (NASDAQ: MSFT)

While not a pure-play quantum stock, Microsoft is a major force in the industry through its Azure Quantum platform.

In February 2025, Microsoft announced a breakthrough in quantum chip design with the introduction of “Majorana 1,” the world’s first quantum chip built with a topological core architecture. This marks a significant leap toward scalable and stable quantum computers—one of the biggest hurdles in the industry.

Alphabet Inc. (NASDAQ: GOOGL)

Google, through its parent company Alphabet, has long been a pioneer in quantum computing research.

The tech giant recently unveiled “Willow,” a next-generation quantum computing chip, reinforcing its commitment to pushing the limits of quantum technology. Google’s efforts could have huge implications for artificial intelligence, cryptography, and scientific computing.

Should You Invest in Quantum Computing Stocks?

Quantum computing is still in its early stages, meaning the sector remains highly volatile. However, recent breakthroughs suggest commercial applications could be closer than many previously thought.

For investors willing to take on some risk, companies like Rigetti, D-Wave, and IonQ offer direct exposure to the field, while Microsoft and Alphabet provide more stable entry points into quantum computing through their diversified businesses.

As the industry continues to evolve, quantum computing stocks could become some of the most valuable tech investments of the next decade. Whether or not the technology lives up to its full potential, one thing is certain—quantum computing is no longer science fiction; it’s happening right now.
