+ 11. **Gilles Brassard (1984)**  
+   * Co-founder of the BB84 protocol, the first functional quantum cryptography system. The BB84 protocol is a quantum key distribution (QKD) protocol that allows two parties to securely exchange cryptographic keys over a potentially insecure channel. The security of BB84 relies on the principles of quantum mechanics, particularly quantum superposition and the no-cloning theorem.
