Nvidia CEO: Quantum Computers Won't Be Very Useful for Another 20 Years

Nvidia CEO Jensen Huang said quantum computers won't be very useful for another 20 years, causing stocks in this emerging sector to plunge more than 40% for a total market value loss of over $8 billion. 'If you kind of said 15 years for very useful quantum computers, that'd probably be on the early side. If you said 30, is probably on the late side. But if you picked 20, I think a whole bunch of us would believe it,' Huang said during a Q&A with analysts. PCMag reports: The field of quantum computing hasn't gotten nearly as much hype as generative AI and the tech giants promoting it in the past few years. Right now, part of the reason quantum computers aren't currently that helpful is because of their error rates. Nord Quantique CEO Julien Lemyre previously told PCMag that quantum error correction is the future of the field, and his firm is working on a solution. The errors that qubits, the basic unit of information in a quantum machine, currently make result in quantum computers being largely unhelpful. It's an essential hurdle to overcomeâ'but we don't currently know if or when quantum errors will be eliminated.

Chris Erven, CEO and co-founder of Kets Quantum, believes quantum computers will eventually pose a significant threat to cybersecurity. 'China is making some of the largest investments in quantum computing, pumping in billions of dollars into research and development in the hope of being the first to create a large-scale, cryptographically relevant machine,' Erven tells PCMag in a statement. 'Although they may be a few years away from being fully operational, we know a quantum computer will be capable of breaking all traditional cyber defenses we currently use. So they, and others, are actively harvesting now, to decrypt later.' 'The 15 to 20-year timeline seems very realistic,' said Ivana Delevska, investment chief of Spear Invest, which holds Rigetti and IonQ shares in an actively managed ETF. 'That is roughly what it took Nvidia to develop accelerated computing.'
