Quantum Computing Inc. (QUBT) saw its stock price plummet 18.12% in Wednesday's pre-market trading following comments from Nvidia CEO Jensen Huang that raised doubts about the near-term potential of quantum computing technology.

During a keynote address at a technology conference on Tuesday, Huang questioned the ability of quantum computers to outperform classical computers in the coming years. He specifically stated that practical, "very useful" quantum computers are likely 15 to 30 years away, with the most optimistic timeline being 15 years.

Huang's remarks sparked concerns among investors about the viability and prospects of quantum computing companies like QUBT, which is focused on developing quantum computing systems. The steep pre-market sell-off in QUBT's stock reflects the market's sensitivity to high-profile comments from industry leaders like Huang, whose opinions can significantly influence investor sentiment and trigger volatility in emerging technology sectors such as quantum computing.
