 Secure Communication based on Quantum Cryptography

Secure Communication based on Quantum Cryptography utilizes principles of quantum mechanics to enable secure transmission of information. The core idea is to leverage the unique properties of quantum bits (qubits) and quantum phenomena such as superposition and entanglement to enhance the security of communication protocols. ### Key Concepts 1. **Quantum Bits (Qubits):** Unlike classical bits, which represent either a 0 or a 1, qubits can be in a superposition of both states simultaneously.
