Quantum Computing Is Coming for Your Digital Secrets

Quantum computing poses a significant threat to digital security, as it could potentially crack encryptions protecting sensitive data. Experts like Gilles Brassard, who helped develop the BB84 protocol, warn of the impending 'Q-Day' when quantum computers become a reality. While quantum computers offer immense computational power, they also enable new forms of attacks, such as 'Harvest Now, Decrypt Later'. Efforts to develop quantum-resistant cryptography and quantum key distribution are underway, but the timeline for these advancements remains uncertain, leaving our digital secrets vulnerable.
