Jensen Huang suggested that practical quantum computing may still be 15 to 30 years away, he reignited skepticism about the technology’s readiness. This perspective has led to significant declines in quantum computing stocks, with companies like Rigetti Computing, D-Wave Quantum, IonQ and Quantum Computing Inc. experiencing substantial drops.

While Huang’s remarks might apply to fully scalable, general-purpose quantum systems, they ignore the tangible value quantum computing is already delivering today.

Proponents of quantum computing claim it will be able to solve problems that current computers can’t, leading to potential breakthroughs in areas like medicine, science and .

Could it help unlock the universe's deepest secrets?

Bitcoin’s record high value of more than $106,000 is under threat by ever-evolving quantum computing that could undo its foundational encryption, some computational science experts say. If the cryptocurrency wants to avoid an attack that would overhaul its means of protecting transactions, it would need to undergo a costly—and time-consuming—update process that could take nearly a year, according to new research.

Perez-Delgado doesn’t see his research as “certain doom” for Bitcoin. The cryptocurrency has other options to handle a major update, including de-throttling, or speeding up, its block time, or time necessary to move or update transactions to the blockchain. But like the solution of implementing downtime to update the blockchain, speeding up the block time could come at the expense of the platform’s ability to handle user traffic.

“Those side effects are well worth the cost,” Perez-Delgado said.
