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.

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

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

Quantum computing has suddenly become a buzzword on Wall Street. Ever since Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) reported that it hit a new milestone with Willow, its new quantum chip, quantum stocks have been soaring.
