Summary
Quantum Key Distribution has become a flashpoint in global security strategy. Recent signals like Google’s stance favoring post-quantum cryptography over QKD show industry momentum around software-based defenses. Governments are split, with some investing in national QKD networks while others question its practicality and prioritize PQC.
In the United States and close allies, the message is clear. NSA says it does not support using QKD to protect national security systems, and together with NIST is driving PQC standardization that runs on today’s classical networks. This treats the quantum threat as a math problem solved with new algorithms instead of new physics. The result is a policy divide that will shape budgets, interoperability, and timelines for quantum-safe communications.
