Several of these quantum computing stocks could be huge winners over the next decade and beyond.Big ideas often attract big money. And big money can lead to big market caps for companies that turn those big ideas into reality.We're arguably in the early stages of seeing that happen with quantum computing. The technology holds the potential to revolutionize multiple industries. Global consulting firm McKinsey projects the quantum computing market size could reach as high as $131 billion by 2040. If McKinsey ...

What do Berkshire Hathaway (BRK.A -1.16%) (BRK.B 0.18%), Palantir Technologies (PLTR -2.46%), and Tesla (TSLA -1.69%) have in common? Not much. However, they're all large-cap companies that have achieved significant success in recent years. There's one common denominator we can definitely cross of the list: None of these three companies has quantum computing developments underway. But another tech giant does. And I predict it will be worth more than Berkshire, Palantir, and Tesla combined by 2030. A potenti ...

Theoretical physicist Richard Feynman once said, "I think I can safely say that nobody understands quantum mechanics." Feynman, by the way, shared the 1965 Nobel Prize in physics for his work in quantum electrodynamics. If he said no one understood quantum mechanics, then no one understood quantum mechanics. I bring this up for two reasons. First, quantum computing -- one of the hottest technologies around right now -- is based on quantum mechanics. Second, Warren Buffett has been credited with saying, "Nev ...

Core Insights - There is significant interest in quantum computing, with stocks like IonQ and D-Wave Quantum experiencing substantial price increases over the past year, but billionaires are focusing on Alphabet instead [1][3]. Group 1: Billionaire Investments - Billionaires, including Israel Englander, Ken Griffin, and David Tepper, have significantly increased their stakes in Alphabet, with Englander's Millennium Management buying over 2 million shares, a 151% increase [5][6]. - Citadel Advisors, led by Ken Griffin, raised its position in Alphabet by nearly 56% during the same period [6]. - Tepper's Appaloosa Holdings acquired more than 128,000 additional shares, making it his sixth-largest holding [6].
