Quantum computers capable of breaking current encryption do not exist yet, but the threat of 'harvest now, decrypt later' attacks is forcing a global transition. Security experts are now deploying hybrid systems that combine traditional elliptic curve cryptography with new lattice-based schemes to ensure data remains secure even if quantum technology matures in the coming decades.
Key insight: Modern web traffic, including connections to Google, already uses hybrid key exchanges like Kyber, which combine traditional and post-quantum algorithms to hedge against future decryption risks.
