The cybersecurity community is buzzing about the recent announcement that **Charles Bennett** and **Gilles Brassard** will receive the prestigious **Turing Award** in 2026 for their groundbreaking work in quantum cryptography. **A Critical Look Back** However, not everyone is convinced of its immediate relevance. Security expert **Bruce Schneier**, in a 2008 essay titled "Quantum Cryptography: As Awesome As It Is Pointless," expressed skepticism about the technology's commercial value. > While I like the science of quantum cryptography—my undergraduate degree was in physics—I don’t see any commercial value in it. I don’t believe it solves any security problem that needs solving. I don’t believe that it’s worth paying for, and I can’t imagine anyone but a few technophiles buying and deploying it. Systems that use it don’t magically become unbreakable, because the quantum part doesn’t address the weak points of the system. **The Weakest Link** **Schneier** argued that cryptography is only as strong as its weakest link, and the real vulnerabilities lie in areas like computer security, network security, and user interfaces, not in the cryptographic algorithms themselves. He posited that focusing on these weaker areas would yield a greater security return than investing in quantum cryptography. > Security is a chain; it’s as strong as the weakest link. Mathematical cryptography, as bad as it sometimes is, is the strongest link in most security chains. Our symmetric and public-key algorithms are pretty good, even though they’re not based on much rigorous mathematical theory. The real problems are elsewhere: computer security, network security, user interface and so on. **Quantum Computing Concerns?** Addressing concerns about quantum computing potentially breaking current cryptographic methods, **Schneier** remains unconvinced, stating that the math is ahead of the physics. He believes reports of progress in quantum computing are often overblown and emphasizes the importance of crypto-agility in systems to mitigate any future risks. > What about quantum computation? I’m not worried; the math is ahead of the physics. Reports of progress in that area are overblown. And if there’s a security crisis because of a quantum computation breakthrough, it’s because our systems aren’t crypto-agile.
