Quantum computing-related stocks, including Rigetti Computing ( RGTI ), Quantum Computing ( QUBT ), and D-Wave Quantum ( QBTS ), plunge after Meta ( META ) CEO Mark Zuckerberg said practical applications for the tech are far away.

"I'm not really an expert on quantum computing, but my understanding is that's still quite a ways off from being a very useful paradigm," Zuckerberg said on the Joe Rogan Podcast.

Quantum computing stocks are extending losses from last week when Nvidia ( NVDA ) CEO Jensen Huang made a similar point that useful applications are likely decades away.
