Q-Day: The Day the Internet’s Secrets Could Be Broken: How Quantum Computers Could Transform Cybersecurity, Encryption, Banking, and Digital Privacy

By: Zahid Ameer

Q-Day: The Day the Internet's Secrets Could Be Broken explores the coming quantum computing revolution and its potential to transform cybersecurity, encryption, banking, digital privacy, and the global internet. Discover how quantum computers, qubits, superposition, quantum algorithms, and Shor's algorithm could threaten widely used public-key cryptography such as RSA and elliptic-curve cryptography (ECC). This fascinating and accessible book examines the meaning of Q-Day, the race to build cryptographically relevant quantum computers, the "harvest now, decrypt later" threat, quantum hacking, cyberwarfare, digital signatures, secure communications, financial systems, cloud computing, critical infrastructure, national security, and the future of online privacy. Learn why governments, banks, technology companies, cybersecurity experts, and organizations worldwide are preparing for post-quantum cryptography and quantum-safe security. Explore how post-quantum encryption, quantum-resistant algorithms, quantum key distribution, and new cybersecurity strategies could protect sensitive data in a post-Q-Day world. Written for curious readers, technology enthusiasts, cybersecurity professionals, business leaders, students, entrepreneurs, and anyone concerned about the future of digital trust, this knowledge-rich guide reveals why Q-Day could become one of the most consequential turning points in the history of computing and internet security.
