Quantus released a report arguing that advances from Google and IBM have compressed the timeline for a potential attack on crypto public-key cryptography to 2030, according to a May 30, 2026 tweet from CoinMarketCap. The report points to improvements in error correction, qubit stability, and computational efficiency as reasons for the revised projection. Previous estimates suggested cryptocurrencies had decades before facing serious quantum risks. Most cryptocurrencies rely on public-key cryptography to secure wallets, validate transactions, and protect ownership records across decentralized networks.
Quantus Report Cites Google and IBM Quantum Advances
The Quantus report highlights developments from Google and IBM as key reasons for revising projections. Google and IBM have invested heavily in pushing the boundaries of quantum computing. The report argues that improvements in error correction, qubit stability, and computational efficiency no longer follow a slow and predictable path.
Quantum Computers Process Information Using Quantum Mechanics
Traditional computers struggle to break cryptographic protections because the calculations require enormous time and resources. Quantum computers operate differently, processing information using quantum mechanics. This allows them to solve certain mathematical problems much faster. Advanced quantum systems could theoretically derive private keys from public keys.
Post-Quantum Cryptography Development Underway
Post-quantum cryptography refers to encryption methods designed to withstand attacks from both traditional and quantum computers. These algorithms rely on mathematical problems that quantum machines cannot easily solve. Governments, technology firms, and cybersecurity organizations have invested heavily in developing these standards.
