• Realistic Physics: Accurate simulation of quantum measurements and basis mismatches
• Error Detection: See how Alice and Bob can detect eavesdropping by comparing measurement results
• Mobile-Friendly: Fully responsive design works on all devices

How It Works

The BB84 protocol, developed by Bennett and Brassard in 1984, uses the fundamental principles of quantum mechanics to create an unbreakable encryption key:

1. Alice prepares qubits in random bases (rectilinear or diagonal)
2. Bob measures each qubit in randomly chosen bases
3. They compare basis choices to establish a shared secret key
4. Eve's interference introduces detectable errors when she tries to intercept

This simulation brings that process to life with beautiful animations and interactive controls.
