Quantum Cryptography and Why It Matters Q-Day: The Quantum Reckoning (Part II): What Breaks, Who Prepares, and the Quantum Boom That Follows, Book 1, (Paperback)

For more than three decades, cryptographers, physicists, and national-security experts have warned about a single moment they call "Q-Day"-the day a cryptographically relevant quantum computer (CRQC) can run Shor's algorithm fast enough to shatter the public-key encryption that protects nearly every secure communication on the planet. Until recently, that day felt comfortably distant, something for the 2030s or beyond.
