Abstract
A quantum direct communication with user authentication and an apparatus using the same. The quantum direct communication method includes performing verification of security of a quantum channel using a preset channel verification probability and a quantum state source generated by a receiver of quantum direct communication, performing user authentication using one or more of a preset user authentication probability, the quantum state source, and an authentication key shared between the receiver and a sender, stopping quantum direct communication and resetting the quantum channel when the verification of security of the quantum channel fails, and stopping quantum direct communication when the user authentication fails.
