07:33 AM EST, 01/14/2025 (MT Newswires) -- Rigetti Computing ( RGTI ) , Quantum Computing ( QUBT ) and D-Wave Quantum ( QBTS ) shares fell sharply on Monday after Meta Platforms' ( META ) CEO Mark Zuckerberg expressed doubts about the near-term practicality of quantum computing technology.

During an appearance on the Joe Rogan Experience podcast, Zuckerberg reportedly said that quantum computing was "still quite a ways off from being a very useful paradigm."

Rigetti shares fell 32%, while Quantum Computing ( QUBT ) saw a 27% drop and D-Wave Quantum ( QBTS ) was down by more than 33%. Shares of all three companies were up 2% to 5% in premarket trading on Tuesday.

Zuckerberg's comments echoed those by Nvidia ( NVDA ) CEO Jensen Huang, who said last week that "very useful quantum computers" could be 20 years away.

Rigetti Computing ( RGTI ), Quantum Computing ( QUBT ), and D-Wave Quantum ( QBTS ) did not immediately respond to requests for comment from MT Newswires.
