DNA-Quantum is also a new idea which is introduced here for the first time in the history. It is also called quantum biocomputing. The arithmetic operations have discussed here in such a way which have never been described before. There are two cross-platform environments with quantum computing and DNA computing. One is quantum-DNA computing, and another is DNA-quantum computing. In the previous chapter, arithmetic operations in quantum-DNA computing have been discussed already. This chapter will describe another innovative unique idea for cutting-edge technology which is called DNA-quantum arithmetic operation.
