One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits could simultaneously store more information than the number of particles in the known universe.

Getting in early on such a game-changing technology just might be the perfect example of how to make money by being in the right place at the right time. Investing in these three quantum computing stocks, in particular, could be a once-in-a-lifetime opportunity.

While error correction should become more effective as the number of physical qubits in a logical qubit increases, adding more physical qubits to a logical qubit also adds more noise. Much progress has been made in addressing this and other noise issues in recent years, however.

HSBC and IBM demonstrate the world’s first empirical evidence of quantum computing enhancing algorithmic bond trading, achieving up to 34% improvement with hybrid quantum-classical models.

HSBC says trials with IBM’s latest quantum processor offer the first empirical evidence that quantum hardware can deliver real-world value in financial markets.

Rigetti jumped 84% in September, outpacing every other quantum stock. Spoiler alert: The contracts behind the surge may not justify the billions added to its market cap.

In this article, we will discuss quantum computing and how it complements AI, including its ability to enhance AI models, and conversely, also explore AI’s ability to strengthen the power of quantum computing.

For decades, quantum computing has felt like something out of science fiction — abstract, theoretical, and always “10 years away.” But in 2025, the story has changed. Quantum technology is no longer confined to research labs and whiteboards.
