It’s been more than two decades since quantum computing was first developed, but Wall Street has started to warm up to the technology’s long-term prospects. Several pure-play stocks went public in 2021, when investor sentiment was sky-high.
Quantum computing technology harnesses the power of quantum mechanics, utilizing effects like superposition — the phenomenon that occurs at the subatomic scale in which objects have no clearly defined state. It’s exciting because this field of research promises to accelerate computing speed by an order of magnitude greater than what’s possible today.

However, while quantum computing has made great strides in just a few years, the technology is still mostly in the research and development stage. Quantum computers are continually improving and becoming more affordable to develop, and the advent of cloud computing is making quantum technology even more accessible for researchers and software developers. Computing power needs are ballooning as the digital economy and artificial intelligence (AI) expands, with spending on global cloud computing alone predicted to rise to $1 trillion annually within the next decade. Quantum computing could emerge as a key technology by the end of the 2020s as the cloud and AI continue to develop rapidly.

Best quantum computing stocks in 2023
Quantum computing pure-play companies are few. Some very tiny, high-risk businesses like Rigetti Computing (RGTI -13.23%) went public early in the pandemic but are now approaching penny stock status. A number of companies creating software for quantum computers also exist, such as security software start-up Arqit Quantum (ARQQ -4.07%) and Quantum Computing (QUBT -0.77%). A quantum computing ETF is also available to get more general exposure to this nascent industry.
Nevertheless, many larger tech businesses and semiconductor designers are increasing their activity in the quantum realm. Here are some top companies with a hand in the actual development of quantum computers:
| Company | Market Capitalization |

1. IonQ
1. IonQ
IonQ went public via a merger with the special purpose acquisition company (SPAC) dMY Technology Group III in 2021. IonQ is a start-up-stage quantum computing company, and it’s the first quantum computing pure-play (all it does is quantum computing development) company to become publicly traded.
IonQ develops quantum computing hardware and is the first to have its computing systems available via all the major public cloud services. It plans to build a network of quantum computers accessible via the cloud and is targeting rapid growth in 2023 as researchers begin using its hardware at greater scale.
IonQ’s orientation toward cloud computing is illustrated by its partnerships with Microsoft, Amazon‘s (AMZN 0.03%) Web Services (AWS), and Google Cloud. The Japanese telecommunications company and tech investor Softbank Group (SFTBF 4.03%) also has invested in IonQ and is partnering with the company to bring quantum computing power to the many other tech companies in its portfolio. IonQ’s most powerful computer, Aria, is now available via an Amazon AWS service.
IonQ generates little in the way of revenue right now and is not yet profitable. It will need to continue spending heavily to develop its products and business for at least a few more years. Investing in this start-up is a speculative play. The stock could be the most profitable way to invest in quantum computing if IonQ is successful, but investors should act with prudence, given that this is still a start-up business.
2. Microsoft
2. Microsoft
The software titan researches and develops all sorts of technology, and quantum computing technology is no exception. Quantum computers need special refrigeration, hardware designed at microscopic levels, and special software, all of which Microsoft is developing in its labs. Via its massive cloud platform Azure, Microsoft also offers access to quantum computing services for researchers.
Quantum computing tech probably won’t be a significant driver of Microsoft’s financial performance anytime soon. However, the company is nonetheless helping to develop the next generation of computing technology. Plus, Microsoft stock has been a winning investment for decades, and its importance in the software technology field will persist for a very long time.
3. Alphabet
3. Alphabet
Alphabet subsidiary Google, also the third-largest public cloud computing platform, has developed its own quantum computing chips branded as Sycamore. The tech behemoth is using quantum computing to advance its artificial intelligence (AI) software systems. It also spun off its quantum computing software unit into an independent startup called SandboxAQ in March 2022.
Google’s interest in better, faster, and smarter methods of computing stems from its leading role in internet search. The company is responsible for organizing massive amounts of digital data, and it can profit significantly by helping organizations of all types to leverage the power of that information. Quantum computing coupled with AI may provide a way for Google to improve the efficiency of large computing systems and is central to the company’s efforts to innovate.
4. Nvidia
4. Nvidia
Nvidia has emerged as the global leader in advanced semiconductor designs, powering next-gen tech with its graphics processing units (GPUs) that accelerate computing power. Nvidia is helping develop quantum computers using its GPUs, retaining its leadership role in developing sophisticated circuitry design. The company is also a leader in AI and machine learning.
Nvidia is leveraging its software developed for GPUs to support the development of quantum computing. It has released cuQuantum, a software development kit designed to help software developers build workflows on quantum computing.
On the hardware side, Nvidia announced DGX Quantum in early 2023. This system pairs Nvidia’s most advanced GPUs with quantum hardware developed by startup Quantum Machines and is made for researchers advancing quantum computing technology. Uses for Nvidia’s quantum work are wide-ranging, from breakthroughs in jet engine efficiency to rapid drug and healthcare development.
