  Quantum communication in general helps deter potential eavesdropping in the
course of transmission of bits to enable secure communication between two or
more parties. In this paper, we propose a novel quasi-deterministic secure
quantum communication scheme using non-maximally entangled states. The proposed
scheme follows a simple procedure, and cases where the entanglement required
can be significantly reduced to carry out the protocol successfully are
discussed. Long sequences or the whole sequence of data can be sent after error
checking for a potential eavesdropper. The maximum qubit efficiency of the
proposed protocol is found to be 33.333%.
