- Gilles Brassard met Charles H. Bennett in 1979, leading to a collaboration on quantum cryptography.
- Bennett proposed a method for unbreakable encryption based on quantum physics, now essential in the quantum age.
- Bennett and Brassard were awarded the 2025 A.M. Turing Award for their contributions to quantum computing.
- Quantum information cannot be copied, making it inherently secure against eavesdropping.
- The BB84 protocol, developed in 1984, allows secure key exchange using single photons.
- Peter Shor's 1994 algorithm showed quantum computers could break classical encryption, increasing the urgency for quantum cryptography.
- Bennett built the first quantum cryptography machine in 1989, demonstrating practical applications.
- Quantum teleportation, introduced in 1993, transfers quantum states using entanglement.
- IBM continues to build on Bennett's foundational work in quantum computing and security.
