Post-Quantum Cryptography Is the First Real Quantum Market
Why quantum risk is already reshaping cybersecurity, compliance and digital infrastructure
Post-quantum cryptography is becoming the first operational quantum market not because fault-tolerant quantum computers are already commercially mature, but because the risk they will eventually create is already changing present decisions. Governments, banks, cloud providers, telecom operators, defence organisations and critical infrastructure providers cannot wait for a cryptographically relevant quantum computer to appear before acting. Their exposure lies in the long life of sensitive data, the depth of existing public-key cryptography in digital systems, and the time required to identify, replace and validate vulnerable cryptographic infrastructure.
