Google's quantum chip Willow has just demonstrated "quantum advantage," producing consistent results, which is a milestone in the history of quantum computing. Even more exciting, Elon Musk commented on X: this indicates that quantum computing is moving toward commercial viability.

Here's the interesting part—the quantum concept stocks IonQ, Rigetti, and D-Wave have surged far beyond the market in the past three months, but they have little to no real revenue, are burning cash at a rapid rate, and executives are aggressively reducing holdings and raising funds. In contrast, tech giants like Microsoft, Amazon, IBM, and Google have long been invested in quantum technology; their AI businesses are already quite stable, and quantum is just an additional surprise.

In other words, those pure quantum concept stocks are more like meme coins driven by FOMO sentiment, with extremely high risks. If you really want to bet on the dual concept of quantum + AI, choosing large-cap companies is safer.
