Several companies are excited about the prospects of quantum computing and how it can transform how we do business.McKinsey &amp; Company estimates that the quantum computing market could be worth up to $72 billion annually by 2035. That's a major market opportunity to capture. There are several competitors in this space, but I think three stocks are primed to do well. If you're looking to get started investing in quantum computing, I think these three make for an excellent core to build a section of your portfolio around.Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an &#34;Indispensable Monopoly&#34; providing the critical technology Nvidia and Intel both need.

Quantum computers use particles to perform computations, and measuring what's happening at the atomic level is difficult in the presence of significant background noise. So inaccuracies can easily enter a calculation. Every company in the quantum computing space is trying to solve this problem, but nobody has technology as accurate as IonQ (NYSE: IONQ). While most companies struggle to reach 99.9% accuracy, IonQ has already achieved 99.99%. As computing systems get larger, errors can compound. As a result, many available quantum computing devices are relatively small and cannot handle large workloads. However, IonQ is building a 256-qubit quantum computer using the same technology that enabled 99.99% accuracy. If this computer is successful, it puts IonQ on the fast track to becoming one of the top quantum computing investments.<h2>Alphabet</h2>Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) is one of the legacy tech companies competing in quantum computing, and it has announced several breakthroughs. Alphabet is self-funding its quantum research, unlike others that must raise capital from the public markets. If it can develop a viable quantum computer, it already has the infrastructure set up to monetize it via Google Cloud.This makes Alphabet a safe bet, as even if its quantum chip fails to gain traction, it could still fill its data center with computers from IonQ and make money renting out its capabilities to clients via the cloud. That makes Alphabet a no-brainer investment in this space.<h2>Nvidia</h2>Last is Nvidia (NASDAQ: NVDA), which is solely focused on traditional computing units. However, it recognizes that quantum computing will affect the future, so it's doing several things to ensure that its computing units are used in the process. Nvidia believes that future computing will be a hybrid of traditional and quantum methods. This hybrid approach will require existing computing infrastructure, which is dominated by Nvidia graphics processing units (GPUs).In order to stay on top, Nvidia has tweaked its leading CUDA software to include quantum functions and renamed it CUDA-Q. It has also developed a generative artificial intelligence (AI) model to help with error correction, further advancing many companies' accuracy scores. It has also created NVQLink, which allows quantum computers to plug into existing computing networks. All of this showcases that Nvidia is looking to bridge the gap between traditional and quantum computing methods. This is a great place to be, and Nvidia will still be a great investment even after the AI build-out is over and quantum computing hits the mainstream.<h2>Should you buy stock in IonQ right now?</h2> Before you buy stock in IonQ, consider this: The Motley Fool Stock Advisor analyst team just identified what they believe are the 10 best stocks for investors to buy now… and IonQ wasn’t one of them.
