Post-Quantum Cryptography
The machines that will break the encryption protecting everything you own are already being built.
Quantum computing is advancing faster than most people realize. When large-scale quantum computers arrive, the cryptographic algorithms that currently protect banking, healthcare, national security, and every private message you send will become solvable in hours rather than millennia.
Post-quantum cryptography is the response: new mathematical foundations designed to resist both classical and quantum attacks. The transition is already underway. NIST finalized its first post-quantum standards in 2024. If you work in cybersecurity, data privacy, or any field that depends on encryption, this is the most consequential shift of the next decade.

Brian Cox on Quantum Mechanics
Adversaries are already harvesting encrypted data with the intent to decrypt it once quantum capability is available. The strategy is called "harvest now, decrypt later," and it means the threat timeline isn't when quantum computers arrive. It's today.
Understanding the fundamentals of quantum computing isn't optional for anyone working in security or privacy. It's the prerequisite for every conversation that follows.
