Quantum computing is revolutionizing technology, offering cutting-edge solutions to problems beyond the capabilities of traditional computing. As we approach 2026, this groundbreaking technology is entering a pivotal phase, with increased scalability, real-world applications, and growing national security significance. Governments and enterprises are allocating significant resources into quantum advancements, making it an exciting time for investors looking to capitalize on this transformative sector. Below, we spotlight three quantum computing stocks poised for significant growth in the coming years. IonQ is leading the charge in the quantum computing space with its impressive growth trajectory and groundbreaking advancements in high-fidelity trapped-ion systems. Through its acquisition of Oxford Ionics, IonQ is surpassing 64 qubits, cementing its place as a major player in scalable quantum hardware.

The company’s revenue model is diversifying, placing a greater emphasis on enterprise and government contracts. In Q3 2025, IonQ reported $39.9 million in revenue, a remarkable 222% year-over-year growth. Despite aggressive investments resulting in a $1.1 billion net loss, the company raised its 2025 revenue forecast to $106-$110 million. IonQ’s shares are currently trading at $46, reflecting a >6% growth year-to-date. Investors seeking exposure to a pure-play quantum hardware provider should closely monitor this stock. D-Wave Quantum takes an innovative approach, prioritizing real-world use cases over theoretical capabilities.

Imagine a future where computers solve problems that currently baffle even the most advanced supercomputers – that's the tantalizing promise of quantum computing, and it's shaking up the tech world right now. With just $1,000 to invest, you might wonder where to put your money in 2026. But here's where it gets exciting: we're talking about stocks tied to quantum AI, a field blending artificial intelligence with quantum tech that could unlock trillions in value. And this is the part most people miss – it's not just about futuristic gadgets; it's about practical revolutions in drug discovery, logistics, energy management, and financial risk assessment. Stick around, because I'm about to reveal my top three quantum computing investments that could be smart long-term bets, explained in a way that's easy to grasp even if you're new to the concept. First off, let's talk about the backdrop.

Over the past three years, investors have watched generative AI – think tools like those from OpenAI or major cloud providers – transform how businesses and governments operate, streamlining workflows in virtually every sector. As AI integrates deeper into corporate life, tech giants are ramping up investments in chips and data centers. Yet, lurking beyond these developments is quantum computing, a cutting-edge technology still in its experimental phase. For beginners, imagine quantum computing as a super-powered calculator that uses the weird rules of quantum physics to process information exponentially faster than traditional computers. Enthusiasts believe it could revolutionize fields like creating new medicines, optimizing supply chains, predicting energy needs, and evaluating financial risks. In fact, consulting experts at McKinsey & Company estimate it could generate up to $2 trillion in economic benefits by the end of the next decade.

But here's where it gets controversial – is this hype or reality? Critics argue quantum computing might take decades to become practical, potentially leaving investors holding overhyped assets. What do you think? Could we see quantum breakthroughs sooner than expected, or is this just another tech bubble waiting to burst? Where should you put that $1,000 today? Our analyst team has just uncovered what they see as the 10 best stocks to buy right now.

Dive in here to learn more. With that in mind, I'll share my top three picks for quantum AI stocks heading into 2026, each offering a compelling case for long-term growth. These aren't speculative gambles; they're plays on established tech leaders already dominating AI. Alphabet (NASDAQ: GOOGL and GOOG) stands out as one of the most promising mega-cap AI investments available. Its sprawling business empire includes search engines, online ads, cloud services, gadgets, self-driving tech, and even custom-designed chips – all woven together in a vertically integrated model. This means Alphabet connects its products and services so tightly that AI powers every aspect of its operations.

For example, think of how its search engine uses AI to deliver personalized results, or how its cloud platform supports businesses with AI-driven analytics.
