Quantum computing concerns have resurfaced across the crypto industry as major technology firms accelerate research and investment ahead of 2026.
Despite growing attention, experts widely agree that quantum computers will not be capable of breaking Bitcoin’s cryptography next year.
The renewed debate follows announcements such as Microsoft’s unveiling of its Majorana 1 quantum chip earlier this year.
Industry specialists say the real issue is preparation rather than an imminent collapse of blockchain security.
Clark Alexander, co-founder and head of AI at Argentum AI, said quantum computing will have “extremely limited commercial use” in 2026.
The whole ‘quantum threat to Bitcoin’ narrative is 90% marketing and 10% imminent threat… we’re almost certainly at least a decade away.
Nic Puckrin said.
Bitcoin and most blockchains rely on public-key cryptography to secure wallets and validate transactions.
A sufficiently advanced quantum computer could theoretically derive private keys from exposed public keys.
This risk has attracted the attention of regulators, including the US Securities and Exchange Commission.
