| الملخص | The fundamental research of Bennett and Brassard has emerged as a key work when considering the development of the principles of quantum cryptography and communication. The exploration of quantum cryptography is considered one of the supreme visions related to theories of quantum physics to guarantee unconditional security. The unconditional security property is verified by considering the no cloning theory -since the transferred quantum state can't be copied or duplicated. The quantum state can, however, be transmitted. The furthermost applied quantum communication laws are quantum teleportation and dense coding.
The idea of quantum teleportation relies on the quantum state being transferrable among remote users, using both classical communication for maintaining the distribution of measurement outcome, and maximally shared quantum entanglement between remote users. In dense coding, Pauli operations and maximally shared quantum entanglement can be utilised for the transferral of encoded classical information among remote users, since every quantum bit is able to transfer two classical bits. |
