Nvidia CEO warns practical quantum computing is years away, stocks tumble

Nvidia CEO Jen-Hsun Huang stated that practical quantum computers are still many years away, estimating a timeline of 15 to 30 years for their development. His comments led to significant stock drops for several quantum computing companies, losing over $8 billion in market value. Previously, stocks had risen after Google's announcement of a quantum computer that could outperform traditional supercomputers. Huang emphasized that quantum computing excels in specific calculations, particularly in encryption, which is of interest to governments and defense sectors. Despite the stock declines, Huang believes progress in quantum computing will continue. He noted that classical computers are essential for error correction in quantum systems, indicating a collaborative future between the two technologies.
