Quantum computing stocks sold off Monday after Meta Platforms CEO Mark Zuckerberg cautioned that uses for computers with these capabilities remain years away. The comments reinforce recent commentary from Nvidia CEO Jensen Huang that suggested that the computers are likely 15 to 30 years away.

Quantum stocks tumble as Nvidia’s cautious timeline and Zuckerberg’s doubts spark sell-offs, while D-Wave CEO argues quantum tech is delivering value today.

CEO Jensen Huang lit the entire quantum computing sector on fire last night after saying the technology won’t be “very useful” for at least 15 years and maybe as many as 30 years. He may as well have poured gasoline on the industry and thrown in a lit match.
