Quantum Cryptography's Inventors Snag Turing Award—But Does It Fix Anything Real?
Forty-two years after inventing quantum cryptography, Charles Bennett and Gilles Brassard just won the $1M Turing Award. Here's why this honor feels more like a pat on the back for elegant physics than a fix for today's security messes.
⚡ Key Takeaways
- Bennett and Brassard's BB84 protocol detects eavesdroppers via quantum physics, but ignores security's weakest links like users and software.
- Quantum crypto remains commercially pointless after 42 years due to high costs and limited scope.
- Post-quantum classical algorithms will handle quantum threats faster and cheaper than QKD networks.
