Quantum Computing Inc. (NASDAQ: QUBT) just crossed into the green for the year after a 25.4% single-day surge. It is by far the best-performing quantum computing stock today and the poster child for the quantum-computing melt-up that followed Nvidia CEO Jensen Huang’s unexpectedly bullish comments at the GTC Paris conference.

The main news piece as of late was Nvidia CEO Jensen Huang's comments at GTC Paris, stating that "quantum computing is reaching an inflection point" and that the world is "within reach" of using quantum computers for complex problems. These words starkly contradict the tone we heard from Mr. Huang before - hence the reaction across the niche.

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.
