The advent of powerful quantum computers, termed 'Q-Day,' poses a significant cybersecurity threat, potentially rendering current encryption standards obsolete. Unlike the Y2K crisis, Q-Day lacks a defined timeline and its primary danger lies in adversaries actively collecting encrypted data now to decrypt it later. This 'harvest now, decrypt later' strategy means sensitive information could already be compromised, transforming encrypted data into a liability. AI
