Shares of Quantum Computing Inc. (QUBT) plunged 5.79% in the after-hours trading session on Sunday, following comments from Nvidia CEO Jensen Huang that dampened expectations for near-term practical applications of quantum computing technology.

During a Q&A session at Nvidia's Consumer Electronics Show Financial Analyst event, Huang suggested that "very useful quantum computers" are likely at least 15 years away, and potentially as far as 30 years in the future. His remarks cast doubt on the timeline for mainstream adoption of quantum computing, causing a sell-off in related stocks like QUBT.

The news article provides insights into Huang's comments and their impact on the quantum computing sector. It highlights that Huang's statements reiterated his previous views from March 2023, indicating that his position on the long-term timeline for quantum computing remained unchanged. However, investors reacted negatively, suggesting that many were caught off guard or had unrealistic expectations.

The article also notes that while Huang's remarks apply to fully scalable, general-purpose quantum systems, they overlook the tangible value that quantum computing is already delivering in various industries. Early adopters are leveraging quantum computing to optimize logistics, streamline operations, and uncover insights that classical systems cannot achieve.
