China's Quantum Cryptography Push Threatens Global Encryption with "Harvest Now, Decrypt Later" Strategy

China is strengthening its communications by investing in quantum cryptography and developing dedicated computing capabilities for decrypting foreign systems. This asymmetry creates operational risks through the "Harvest Now, Decrypt Later" strategy, targeting current encrypted data for future exploitation. The context involves three key areas: AI, quantum computing, and satellite infrastructures, with a deadline mentioned for 2026. The article highlights a threat to the security of communications and critical infrastructures.
