Several stocks across the quantum computing industry fell sharply Wednesday after Nvidia CEO Jensen Huang said the technology is likely still years away.

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

Last year, investors poured into artificial intelligence (AI) stocks, and the biggest players -- from Nvidia (NASDAQ: NVDA) to Amazon -- helped the general market soar. Quantum computing harnesses the principles of quantum mechanics to solve problems that classical computers can't handle.

The quantum computing revolution is changing technology as we know it. Quantum computers leverage the principles of quantum mechanics to perform calculations far beyond the capabi
