Nvidia CEO Jensen Huang initially suggested that practical quantum computers may not be available for 15 to 30 years, but later emphasized that quantum computing has the potential to revolutionize technology. During Nvidia's annual developer conference, he revised his earlier timeline regarding the utility of quantum computing, expressing surprise at the impact his previous remarks had on the market. Despite his reassurances, stocks in the quantum sector, including D-Wave, experienced significant declines. Meanwhile, Nvidia announced plans to establish a research center in Boston, aiming to collaborate with quantum researchers and demonstrating ongoing interest in the field despite the market's challenges.
