论文摘要
使用动态衍射的量子信息模型，我们考虑了一个由两个完美的晶体硅叶片组成的中子腔，能够包含中子波函数。我们表明，通过Bragg衍射的中子的内部限制可以通过量子随机行走来建模。在模拟和实验实施之间发现了良好的一致性。关于晶体几何和参数，对站立中子波的分析进行了分析。并得出了定义明确的弹跳所需的条件。提出的结果使得使用中子限制的设置可以进行新的方法，例如测量中子磁和电偶极矩的实验。
Using the quantum information model of dynamical diffraction we consider a neutron cavity composed of two perfect crystal silicon blades capable of containing the neutron wavefunction. We show that the internal confinement of the neutrons through Bragg diffraction can be modelled by a quantum random walk. Good agreement is found between the simulation and the experimental implementation. Analysis of the standing neutron waves is presented in regards to the crystal geometry and parameters; and the conditions required for well-defined bounces are derived. The presented results enable new approaches to studying the setups utilizing neutron confinement, such as the experiments to measure neutron magnetic and electric dipole moments.
