Design and Implementation of Encoder/Decoder Quantum Circuits using Decimal to Binary Conversion Method and vice versa

Quantum Computing is an emerging technology. Quantum Computer will mainly focus on the principles of quantum theory. We design some major data processing circuits like encoder and decoder i.e., $16\times 4$ encoder and $4\times 16$ decoder using decimal to binary conversion method and vice versa. Where an encoder is used to encode an incoming signal into an encoded value. A decoder is used in conjugation with the encoder to the decoder, the encoded signals, and recover the original signal. For all the given possible inputs we got probability=1.
