With the advent of efficient quantum algorithms and technological advances, design of quantum circuits has gained importance. In this paper, Quantum circuit using standard quantum gates is constructed for the transmission of quantum encrypted check bits. The proposed scheme is analogous to the first QKD (quantum key distribution) protocol, (BB84) where the check bits are used to detect the level of noise and evesdropping on the channel. The gates used in this work are easily realizable and the encoding and decoding of classical information bits is extended for multiple bits using dense coding scheme.
