| Abstract: | In this paper, we proposed a novel quantum secure direct communication scheme with one-time pad in stabilizer formalism. Based
on the reuse of qubit sequence, an efficient secure communication of secret messages without first producing a shared secret
key can be achieved. One hence may find that the amount of private key needed for quantum communication is smaller than that
in the general case. Therefore, the present protocol which is feasible with the present-day techniques may be applied to quantum
communication with short-length encoding. |
