Story summary

Q-Day poses a significant risk as quantum computers could compromise existing encryption methods.
Unlike Y2K, Q-Day's unpredictable timeline makes preparation challenging.
The National Cyber Security Centre recommends a three-phase migration to post-quantum cryptography by 2035.
Businesses should consider Quantum Key Distribution (QKD) or Post-Quantum Cryptography (PQC), with PQC being the more feasible option.
A balanced strategy is crucial to ensure timely and effective responses to quantum threats.
