Recent algorithmic breakthroughs have dramatically reduced the qubit count needed to crack RSA-2048, from 20 million in 2019 to as few as 10,000 in 2026. Hardware is scaling rapidly, with leading firms targeting 10,000+ qubit machines within 1-2.5 years. The 'harvest now, decrypt later' threat means hostile actors may already be stockpiling encrypted data. Post-quantum cryptography standards exist and NIST has published algorithms, but the window for migration is narrowing. Beyond security threats, quantum computers promise breakthroughs in materials science, drug discovery, clean energy, and fundamental physics. ## Full article daily.dev links to this article rather than hosting it.
