Focusing on the research and application of Quantum Algorithms,this paper was divided into three parts,which were the studying and Nuclear Magnetic Resonance(NMR) simulation of multi-qubit Quantum Algorithms;the design and analysis of classical coupled harmonic oscillators system which corresponded to Grover search algorithm;and,proposing the model of nucleotide base selection and H-bond formation in DNA replication and proteins synthesis,which corresponded to quantum information processing mechanism...
