Nvidia Corp. Chief Executive Officer Jensen Huang said Wednesday that quantum computing is reaching an inflection point and will be powerful enough in the coming years to help “solve some interesting problems” globally.

Earlier this year, Huang sent quantum stocks sliding after he said he believes useful quantum computers were 15 years or more away. He later qualified his remarks and walked them back somewhat, even hosting executives from around the industry to "tell him why he was wrong."

Quantum computing shares are jumping in premarket trading Wednesday after Nvidia CEO Jensen Huang said that the industry was “reaching an inflection point."
