Quantum computing stocks are tumbling after Nvidia CEO Jensen Huang warned that the technology is a long way off.

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.

Quantum stocks like Rigetti, IonQ and D-Wave Quantum saw steep losses after Nvidia CEO Jensen Huang said quantum computers are decades away.

This is what's happening on Wednesday, as quantum computing investors cheer some kind words from Microsoft's strategic missions and technologies chief, Mitra Azizirad, who last night urged quantum investors to get ready, because "we are right on the cusp of seeing quantum computers solve meaningful problems and capture new business value."

The same stocks rallied earlier this week after Microsoft unveiled an initiative meant to familiarize business leaders with quantum systems.
