Quantum-computing stocks tumbled Monday following comments from Meta Platforms CEO Mark Zuckerberg that quantum is far from being a “practical paradigm.”Shares of D-Wave Quantum and Rigetti Computing fell 31% and 29%,

Quantum computing holds the potential to radically transform the world. Nvidia CEO Jensen Huang and Meta Platforms CEO Mark Zuckerberg recently poured cold water on some of the hype surrounding quantum computing.

Quantum Computing didn't have any news of its own to report, but the company is even smaller than D-Wave, with less than $1 million in revenue over the last four quarters. Its stock has soared even higher than D-Wave's over the last year, a disconnect that could lead to a continued decline in Quantum Computing's shares.
