The NSA says it does not support QKD for national security. Read more: https://postquantum.com/post-quantum/qkd-countries-differ/ #PostQuantum #QKD
Quantum Key Distribution (QKD): Why Countries Differ on Its Future
Quantum Key Distribution (QKD) - a method of securing communications using quantum physics - has become a flashpoint of debate worldwide. Recent news (like Google’s announcement favoring post-quantum algorithms over QKD) highlights how divided opinions are. Some nations are investing heavily in QKD networks as the next frontier of secure communications, while others remain skeptical and prioritize post-quantum cryptography (PQC). United States and Allies: Emphasizing PQC Over QKD In the U.S. and allies like the UK the official stance has been to downplay QKD and focus on PQC. U.S. security agencies argue that QKD is impractical for most real-world uses
