Quantum computing threat to Bitcoin may arrive sooner than expected: report
A new quantum computing report has warned that the cryptocurrency industry may be running out of time to prepare for cryptographic attacks that could eventually threaten more than $2 trillion in digital assets.Quantus warned that quantum computing progress has accelerated faster than much of the crypto industrys post-quantum planning.The report said millions of lost Bitcoin could become exposed because inaccessible wallets cannot migrate to quantum-resistant addresses.Researchers behind the report said recent advances from Google and other quantum firms have reduced the estimated resources needed to break Bitcoins cryptography. According to “The State of Quantum” from Quantus, shared with crypto.news, recent breakthroughs in quantum hardware and error correction have compressed expectations around when cryptographically relevant quantum computers could emerge. The report argued that the threat is no longer theoretical because the mathematical path for breaking elliptic curve cryptography, the system securing Bitcoin and most blockchains, has already been understood for decades. Researchers behind the report pointed to a series of developments from Google, IBM, and Quantinuum between 2024 and 2026 that they said changed how experts view the timeline. Among the most significant was Google Quantum AI‘s March 2026 paper, which estimated that Shor’s algorithm could break the secp256k1 elliptic curve used by Bitcoin with
