This video explains the threat quantum computers pose to modern internet encryption and the ongoing effort to implement quantum-resistant security standards.

As quantum computing technology advances, existing encryption standards protecting the internet face obsolescence by 2029, a milestone known as 'Q-Day'. This vulnerability threatens global digital infrastructure, financial systems, and private communications, as malicious actors are already harvesting encrypted data today for future decryption. Consequently, a global shift toward post-quantum cryptography is underway to secure digital services against these future threats.
