Quantum computing is a burgeoning technology that builds multidimensional worlds with immense potential across a variety of sectors. Traditional computers are designed to answer issues more quickly than quantum computers, and these capabilities could affect how companies model chemical interactions, optimize logistics and organize enormous databases.

As quantum computing impacts practically every industry, including military defense and biowarfare, governments have increased investment to prevent falling behind other nations. The European Union and the United States have given $7.2 billion and $1.3 billion, respectively, while China has pledged a stunning $15 billion in government assistance.

Consequently, these are the ten best quantum computing stocks to buy for decade-long returns.

What is quantum computing?

Quantum computing is the most recent technological "final frontier" – a new era of machine problem-solving in which computers work using quantum mechanics. Now, it appears that quantum computing will continue to expand. For instance, D-Wave Systems Inc., a pioneer in quantum computing, will soon go public via SPAC.

However, what is the best way to trade in this baffling yet popular rising market? No one knows what the future of quantum computing will look like, which is fitting. Nonetheless, the following are important essentials to note.

Quantum computing is the use of quantum phenomena like superposition and entanglement to conduct computations. Quantum computers are computers that can conduct quantum calculations. Quantum computers are expected to be able to tackle certain computational tasks, such as integer factorization (which is the basis of RSA encryption), much quicker than classical computers. Quantum information science includes quantum computing as a subfield.


Paul Benioff, a physicist, devised a quantum mechanical model of the Turing machine in the early 1980s, which marked the beginning of quantum computing. Later, Richard Feynman and Yuri Manin hypothesized that a quantum computer could simulate phenomena that a conventional computer could not. Peter Shor created a quantum method capable of decrypting RSA-encrypted communications for factoring integers in 1994. Despite continued experimental development since the late 1990s, the majority of scientists feel that "fault-tolerant quantum computing is still a faraway dream." In recent years, both the public and business sectors have boosted their investments in quantum computing research.

The potential for quantum computing to revolutionize technology is equivalent to that of the first digital computers. Even if advancements have been made, it could be years before quantum computers can be utilized on a big basis. This indicates that investors should see quantum stocks as having a ten-year investment horizon or potentially much longer.

Pure quantum computing players are tough to locate, as many of the most promising organizations are startups that are not yet accessible to conventional investors. Nevertheless, a number of established tech giants, such as IBM, are also participating. Due to the fact that they are openly traded and do not depend only on the success of quantum, they alleviate a portion of the risk associated with trading quantum.

Quantum versus conventional computers

Quantum computing is not "simply another form of computer" despite being difficult to comprehend. Traditional computers are powered by code, whereas the principles of quantum physics power quantum computers.

Simply said, the computers we are familiar with are powered by bits, ones, and zeros that are used to compose instructions in binary "languages" that the computer can interpret. Quantum computers utilize qubits, which are subatomic particles such as electrons or photons, as their power source. Non-linear and capable of performing multiple non-binary functions simultaneously, these can be multiple things.

Quantum computing thereby provides exponentially more processing power, working memory, and sophistication in a far shorter time frame. Quantum computers are capable of solving issues that traditional and even supercomputers were unable to.

Quantum computing is a relatively new field compared to traditional computing, and hence the practical manifestations of quantum machines now vary greatly. For instance, a simple quantum computer is approximately the size of a room. Many operate so rapidly that they require cryostats, which cool them to near absolute zero temperatures, hundreds of degrees Celsius below zero, to work. This is expected to alter as the technology advances, most likely by quantum leaps.

Why invest in quantum computing?

Quantum Computers employ the principles of quantum physics to develop novel, potent methods of doing computations. Quantum technology should be considered a key facilitator for future industries, with applications such as improved approaches for drug development and financial market modeling.

However, the quantum industry is still in its earliest stages. The vast majority of the companies discussed in this article have yet to make meaningful revenue from quantum technology. Over the past decade, these companies have emerged from research labs, acquiring government and private funding and devoting to fundamental research in order to produce truly innovative technology.

Investing in any of these quantum computing stocks requires a basic judgment call: that it is possible to construct usable quantum computers.

Quantum computing may be a relatively small part of Microsoft's overall cloud services and software business, but Bank of America analyst Brad Sills says there are plenty of other reasons to love Microsoft, such as its Office 365 products and gaming division, which will be strengthened if its proposed acquisition of Activision Blizzard Inc. (ATVI) goes through. According to Sills, Microsoft's profit margins will grow even more in the next few years. MSFT stock, which ended on January 14 at $310.20, carries a "buy" rating and a price target of $365 from Bank of America.

6. Alphabet (GOOGL)

Google is one of the most visible sectors of Alphabet, the online media behemoth. Google's principal interest in quantum computing stems from its dominant internet search position.

Alphabet released fourth-quarter 2021 earnings on February 1, 2021. The revenue climbed by 32% year-over-year (YOY) to $75.3 billion. The net income for the quarter was $20.6 billion, or $30.69 per share, up from $15.2 billion in the same period of the prior year. Cash and equivalents reached $20.9 billion at the period's end.

In addition, management announced a 20-for-1 stock split. The date of the split, July 1, is currently anticipated by investors. Many retail purchasers consider these events to be lucrative investment opportunities.

In 2019, Google's Sycamore quantum computing chips completed a task that the company said would have taken a supercomputer 10,000 years to complete. The tech giant intends to develop a "useful, error-corrected quantum computer" by the year 2029.

Google will invest billions over the next decade to develop this technology, which is only natural. The Sandbox division of quantum computing has just been spun off by management.


Over the past year, GOOGL stock has increased by 36%, but it has declined by 3.9% since the beginning of 2022. Shares are trading at a multiple of 24.2 forward profits and 7.3 trailing sales. The median 12-month price prediction for GOOGL stock is $3,500. Following July 1, the split will be reflected in the stock price and analyst estimates.

7. Honeywell International (HON)

The well-known technology company Honeywell manufactures numerous high-tech products, including aerospace equipment, medical gadgets, and innovative materials. Late in November, Honeywell Quantum Solutions merged with Cambridge Quantum Computing to form Quantinuum, the largest quantum computing business.

Wall Street anticipates Quantinuum to go public by 2022's end. Quantinuum's first offering, a cybersecurity solution that is platform- and device-agnostic, appears to thrill investors as well.

On February 3, Honeywell released its Q4 2021 results. Revenue fell 3 percent YOY to $8.7 billion. The net income was $1.43 billion, or $2.05 per share, up from $1.36 a year before. Nearly $11 billion was in cash and equivalents at the end of the period.

The price of HON shares has decreased by around 8% over the past year and 6.8% so far this year. The stock's current price is 22,4 times future earnings and 3.9 times trailing sales. The median price projection for HON stock over the next 12 months is currently $220.

8. Analog Devices (ADI)

Semiconductor manufacturer Analog Devices produces integrated circuits that process analog and digital signals. The chips manufactured by ADI are utilized in data converters, high-performance amplifiers, and microwave-integrated circuits.

Analog Devices released Q4 2021 stats on November 23. The revenue climbed by 53 percent from the previous year to $2.34 billion. Adjusted earnings increased from $1.44 to $1.73 per share. $810 million in free cash flow was created by the corporation. The period concluded with $1.98 billion in cash and equivalents.

The demand for sensors and machine connectivity, which increasingly rely on analog chips, has been spurred by the automation of factories. In addition, the increasing usage of modern electronics in electric vehicles has transformed the automobile industry into a significant growth engine (EVs).

The acquisition of Maxim Integrated was finalized at the end of August. The $1 billion purchase is expected to improve ADI's market dominance in the automotive and 5G semiconductor industries.

Since the early 1990s, device manufacturer NVIDIA has been producing devices. It is most well-known for developing the graphics processing unit (GPU) chip used in traditional computers. Nonetheless, during the past few years, they have also been carefully aligning themselves with prominent participants in the quantum computing field.

Perhaps this is not as much of a reach for the firm as one might believe. Many experts expect that quantum capabilities will not totally replace classical computers, at least not for some time, but will instead be used to augment current capabilities. Thus, quantum computers have the potential to replace GPUs.

Not with their own quantum computers, but NVIDIA has acted accordingly as an ally. In October of 2020, the company released a presentation demonstrating GPU applications for quantum's near-future uses. Then, in November 2021, NVIDIA utilized its own supercomputer to execute the largest simulation of a quantum algorithm ever undertaken, utilizing its own GPUs.

In the same month, it introduced the 'quantum software development kit' in conjunction with IBM and Google's Quantum AI in an effort to accelerate quantum computing research and development. NVIDIA's quantum, a set of libraries and tools designed to expedite quantum computing workflows utilizing NVIDIA technology, is now available to the public as of the beginning of 2022.

Although NVIDIA's plans for its quantum entanglement in the near future are unknown, the market has so far responded positively. Its 2021 year-end statistics included record-high revenues of nearly $7 billion, up more than 50 percent from the previous year. This would indicate that NVIDIA will continue to be a player to watch in the quantum stakes.

10. Rigetti Computing (RGTI)

In October, the full-stack quantum computing company Rigetti Computing announced its desire to go public by combining with SPAC Supernova Partners Acquisition Co. II. Rigetti Computing designs quantum chips, integrates these circuits with a controlling architecture, and produces software used by programmers to create algorithms for the chips.

Chad Rigetti, the CEO and founder of Rigetti, has a Ph.D. from Yale and experience with IBM's quantum computing division. Rigetti asserted audaciously, "Within a decade, a single Rigetti computer may be more powerful than the entire worldwide cloud of today." 

Rigetti Computing is one of the leading developers in quantum technology, aiming to develop a scalable computer and high-performance integration with existing computing systems. Rigetti Computing was valued at approximately $1.5 billion and grossed $458 million from its initial public offering. Rigetti intends to use the transaction's profits to speed the development of future generations of quantum processors and expand its commercial company. By 2026, insiders predict that Rigetti's income will increase to about $600 million.

The bottom line

Experimental research and development on quantum computing are extensive, and all major corporations are investing in platform development. Quantum computing and quantum communication may have an impact on numerous industries, such as healthcare, energy, finance, security, and entertainment. Quantum computing is still in its early phases of development, but a substantial amount of money is being invested in its study. Although pure-play quantum computing stocks are currently uncommon, investing in technology behemoths with quantum computing exposure could generate spectacular returns in the coming decades. Recent analyses project a multibillion-dollar quantum sector by 2030, as the Harvard Business Review reported.
