| 摘 要： | DNA复制和蛋白质合成过程中的核苷酸基配对过程可以看成是无序数据项的搜索问题.量子搜索与经典搜索相比,具有平方根数量级的加速.本文通过符合Grover量子搜索算法的经典谐振子系统和量子隧道效应建立了核甘酸基配对和氢键形成的模型,并从维持量子相干性的角度探讨了DNA聚合酶的催化作用,从信息学的角度论证了生物信息处理的优化.

| Abstract: | The nucleotide base-pairing in DNA replication and proteins synthesis can be looked as an unsorted database search. Compared to the classical search, the quantum search was square root accelerated. Based on the classical coupled harmonic oscillators system, which corresponds to Grover quantum search algorithm, and quantum tunneling effect, the model of the nucleotide base selection and H-bond formation was proposed. In addition, the catalysis of the DNA polymerase was discussed from the point of view of quantum coherence maintained. Finally, the optimization of biological information processing through the point of informatics was proved. |
