QuantumCryptoSim

QuantumCryptoSim is a Python-based simulation toolkit demonstrating the BB84 quantum key distribution (QKD) protocol using Qiskit and Aer simulators. It allows you to:

• Generate random quantum bits (qubits) prepared in different bases.
• Simulate the quantum transmission of these qubits.
• Measure and sift the resulting keys to understand how secure quantum key distribution works.

Features

• BB84 Simulation: Encode and measure qubits in random bases to establish a secret key.
• Key Sifting: Compare bases used by sender (Alice) and receiver (Bob) to extract a shared key.
• Extensible Design: Future support for eavesdropping simulations, error correction, and privacy amplification.
