Nobel Physicist Warns Quantum Computing Could Hit Bitcoin Soon


Nobel Physicist Warns Quantum Computing Could Hit Bitcoin Soon

Share:

AI Overview

Nobel laureate John Martinis (2025) warns advanced quantum computers could break Bitcoin's encryption in minutes, posing a direct crypto security threat. Advances in qubit efficiency indicate quantum threats may arrive sooner than markets expect, raising risks for wallets, keys and protocol integrity. Experts warn rushed cryptographic or protocol updates could weaken Bitcoin more than quantum risk, underscoring need for measured security upgrades and quantum-resistant planning (security, protocol updates, adoption).

  • John Martinis warns that quantum tech could one day break Bitcoin’s encryption in minutes.
  • Advances in qubit efficiency suggest quantum threats may arrive sooner than markets expect.
  • Experts urge caution, warning that rushed fixes could weaken Bitcoin more than quantum risks.

Bitcoin and other cryptocurrencies face a potential threat from quantum computers, warns John Martinis, 2025 Nobel laureate in Physics. Martinis, who led Google’s quantum hardware program, said a sufficiently advanced quantum computer could crack Bitcoin’s encryption in minutes. 

“It’s not something that has zero probability; people have to deal with this,” he stressed in a recent interview. Martinis said that cracking encryption is one of the easier tasks for quantum computers because it relies on straightforward number-based calculations. 

He pointed to Bitcoin as an early tar…
