Apparatus and method for path superposition based quantum secure direct communications

摘要

The present invention relates to a quantum secure direct communication apparatus and method using path superposition, wherein the quantum secure direct communication apparatus using the path superposition is a direct quantum secure communication apparatus comprising a first photon channel, a second quantum channel, And a transmitting end for receiving the single photon from the receiving end, encrypting the single photon, and transmitting the single photon to the receiving end, wherein the receiving end receives the single photon from the transmitting end through an encryption And a cryptographic decoder for receiving and decoding the single photon.
