In this episode of The Quantum Computing Podcast, Lucas and Luna dive into the looming threat quantum computers pose to today's encryption standards—and the race to build quantum-safe cryptography. They unpack a recent NIST report on post-quantum cryptography standards, explain why RSA and ECC are vulnerable, and discuss concrete timelines: when experts like Michele Mosca and the Global Risk Institute predict a 1-in-7 chance of a major cryptographic break by 2026. Lucas breaks down the concept of 'harvest now, decrypt later' attacks, citing real-world examples like the 2023 breach of a major VPN provider. Luna questions whether current transition efforts are fast enough, referencing the UK's NCSC and US Executive Order on cybersecurity. The hosts also explore how quantum key distribution (QKD) and new lattice-based algorithms might offer solutions, while acknowledging the massive infrastructure challenge of replacing every encrypted system. A practical, no-hype look at the most urgent non-quantum application of quantum tech.
