Quantum communication relies on the phenomenon of quantum entanglement, where two or more particles become correlated in such a way that the state of one particle cannot be described independently of the other.

Quantum cryptography aims to provide secure communication by utilizing the principles of quantum mechanics to ensure the confidentiality and integrity of transmitted messages.

The BB84, E91, and B92 protocols are all fundamental protocols in quantum cryptography, each with its own unique characteristics and applications.

Quantum communication offers the potential for unbreakable security due to the fundamental principles of quantum mechanics, such as the no-cloning theorem and the Heisenberg uncertainty principle.

Implementing quantum communication systems presents several challenges, including building reliable quantum devices, developing efficient quantum error correction codes, and distributing entangled particles over long distances.

Quantum communication has potential applications in various fields, including secure communication, unhackable financial transactions, and quantum teleportation.

Quantum communication refers to the process of transmitting information using quantum states, such as entangled particles or qubits.

Quantum communication offers unconditional security, meaning that it is impossible for an eavesdropper to intercept and read the transmitted information without being detected.

The primary difference between quantum cryptography and classical cryptography is that quantum cryptography utilizes the principles of quantum mechanics, such as superposition and entanglement, to provide secure communication.
