依据量子信息学和量子计算基本理论，在研究低剂量I射线与神经细胞的相互作用规律及物理机理时，将神经细胞骨架微管中的两种蛋白构型视为两能级原子体系，使用密度矩阵描述脑神经系统中信息位的状态，建立并求解系统的动力学方程。结果表明：随密度矩阵非对角元素的减小，系统的量子相干性迅速降低。因此，低剂量I辐射可以影响受照者的脑神经功能。

According to the basic theory of the quantum information and quantum computa-tion,a dynamics equation is established and solved to study the characteristics and physical mechanism of the interaction of low doseγirradiation with the cerebral nervous system,in which the two-state physical system in the cytoskeletal microtubule is regarded as a two-level atom system,and the states of information bits in the cerebral nervous system are described by a state-density matrix.The results show that the smaller the non-diagonal elements of the state-dens...
