Day 28　Quantum Protocols and Quantum Algorithms

Quantum Key Distribution
Qiskit

1. Alice generates set of random bits
2. Alice encodes in Z and X-bases at random and sends to Bob
3. Bob measure in same basis Alice prepared
   Without interception -> Bob would be guaranteed to measure 0
4. Bob and Alice reveal basis choices and discard useless bits
5. Bob and Alice compare same random selection to see if qubits were intercepted
