In this piece, we will take a look at the 12 best quantum computing stocks to invest in.

These days, artificial intelligence is one of the hottest topics on the stock market and the media. This is because of the improvements in data analysis and decision making offered by AI models. These have augmented pre AI data analysis and text production technologies, and consequently, Wall Street has piled billions of dollars into the industry.

As AI is to data science, quantum computing is to classical computing. Or at least in some aspects. The fundamental difference between a classical and quantum computer is physics. Classical computers operate under the principles of classic physics, which means that it is easy to determine whether a semiconductor’s processor is in the on (1) or off (0) state. In quantum computing’s case, a transistor’s equivalent is an elemental particle capable of existing in multiple states. So, a quantum ‘transistor’ could be on and off at the same time, to provide programmers with more flexibility to solve problems.

This ability to process more inputs means that quantum computing offers complex problems that traditional computers might not have enough capacity for. This is one reason that some estimates expect the quantum computing industry to be worth a modest $11.4 billion by 2027 despite a rapid compounded annual growth rate of 33%.

At the same time, quantum computing stocks are riskier than even traditional and typically high growth companies. This is because their products do not have sizeable markets and require considerable investment and research and development expenditure which might even take longer to recover than for biotechnology stocks.

These facts also make it trickier to analyze quantum computing stock performance since there are considerably fewer publicly traded companies to offer the convenience of simply seeing how an exchange traded fund has performed. For instance, consider the holdings of the Defiance Quantum ETF (QTUM). Some of its top holdings include software firm MicroStrategy and the memory manufacturer Micron. Neither of these companies generates material income from making products that are essential for a quantum computer to perform. Another major holding is NVIDIA, and while it does make a product for a quantum processing unit’s (QPU) quantum controller, most, if not all of its share price gains have been due to artificial intelligence.

This means that we need to analyze individual quantum computing stocks to see how they have performed recently. Heading into the year’s second half, investors have battled with high inflation, high interest rates, geopolitical tensions, turmoil in banking, and euphoria surrounding artificial intelligence since 2022.

Some quantum computing stocks that are commonly known are Rigetti Computing, Inc. (NASDAQ:RGTI),  IonQ, Inc. (NYSE:IONQ), and D-Wave Quantum Inc. (NYSE:QBTS). Over the past five years, their shares have lost 89%, 24%, and 89%, respectively. Mind you though, this doesn’t mean that quantum computing stocks never go up. For instance, take the example of IonQ. The firm listed its shares for trading in October after a merger, and between October 8th and November 19th, the stock soared by a whopping 233%. For comparison, Wall Street’s AI darling NVIDIA’s shares have gained 239% over the past twelve months.

So, the next question to ask is, what happened to this quantum computing stock? Well, part of the reason is a Goldman Sachs investment note that was released in November 2022. The note wondered when businesses would start adopting quantum computing into their operations, and whether the company’s technology roadmap could align with this shift, as uncertainty persisted over “which forms of quantum computer ultimately captures market share,” according to analyst Toshiya Hari. After losing 14% in the wake of Hari’s comments, the stock would proceed to bottom out over the new year in January, but its performance graph changes when we zoom into 2024’s performance. April 2024 seems to have been the month for IonQ’s shares as the stock is up by 17% since the 19th.

With these details in mind, let’s take a look at the best quantum computing stocks to invest in.
