Quantum computing isn't a faraway technology that has no implications for modern computing practices. Everyone knows it's coming, and there are several applications where quantum computing technology is being deployed right now. I think there are a handful of quantum stocks that are incredible buys right now, and investors should consider adding to them in May.
On my short list, I've got IonQ (IONQ +2.31%), D-Wave Quantum (QBTS +1.01%), and Nvidia (NVDA 0.48%) (yes, Nvidia), and all of them have big upside in the coming months and beyond.

IonQ
IonQ is probably the most popular pure-play quantum computing company out there. It has gained popularity due to its impressive technology. IonQ holds the world record for the most accurate quantum computer, and is significantly ahead of many of its peers in this important factor.
The company was also recently selected as a recipient of one of the government's DARPA (Defense Advanced Research Projects Agency) contracts. Along with other contract winners, this puts IonQ's technology on the fast track to be deployed to military applications, which is a major opportunity for quantum computing.
All of this bodes well for IonQ's future and will give it the resources to continue pursuing its vision of quantum technology. IonQ isn't anywhere close to profitable yet, so it needs all of the funding it can get to pursue its goals and fend off other, well-funded quantum computing competitors. I think IonQ is a phenomenal quantum investment. However, investors need to be patient as it will still be several years before viable quantum computing hits the mainstream.

Key Data Points
D-Wave Quantum
While IonQ is pursuing a general-purpose quantum computer, D-Wave Quantum is working on more specialized ones. These devices use a technique known as quantum annealing, which looks for the lowest-energy state in the system to find the optimal answer. These devices are suited for optimization problems, such as logistic network analysis and schedule creation, two tasks that are already being tackled in the real world.
If D-Wave can continue growing its footprint in the manufacturing world with purpose-built quantum computers that are relevant now, it can become a viable business in the near future. Right now, it's still quite unprofitable, with its revenue only coming in at $24.6 million in 2025 versus total operating expenses of $121 million. It's going to take a bit more adoption before it becomes a viable business, but I have confidence it will, making it a solid quantum stock pick.

Key Data Points
Nvidia
Nvidia may not be the first company you think of when discussing quantum computing stocks. In fact, it's not even building a quantum processing unit. Instead, it believes the future is a hybrid approach, where quantum computers and existing accelerated computing infrastructure work in tandem to optimize computing solutions.
The semiconductor giant is releasing several tools to ensure that its computing units are the ideal choice for the traditional computing side of the hybrid operation. It released an AI model that helps with quantum error correction, has adapted its CUDA software to have quantum-specific models (CUDA-Q), and launched NVQLink, which allows quantum computers to plug into existing accelerated computing networks.

Key Data Points
All of this adds up to a company that's capitalizing on the current AI build-out while positioning itself for a quantum future. With Nvidia still slated to be a major beneficiary of the AI arms race, I think that makes it an excellent buy now. Couple that with a smart and reasonable quantum computing strategy, and I think Nvidia is one of the best buys in the entire market.
