论文摘要
根据三级量子系统的共振，根据最接近哈密顿耦合的任何两个晶格点，电子从高能水平过渡到低能水平并释放光子；或吸收光子并从低能水平到高能级，从而在相等概率的条件下获得沿直线行走的物理过程。然后，将量子步行中的光辐射映射到电场的高斯脉冲中，麦克斯韦方程通过三维有限差分时间域方法求解，以获得空间电动分布。最后，进一步讨论了在两个平行线上行走的物理过程，涉及一些物理特性，例如电磁耦合或相干性，量子状态交换等。可以通过FDTD计算两条线之间的电场耦合，该线为量子设备设计和分析提供了有用的工具。
Based on the three-level quantum system, when it is in resonance, according to any two lattice points closest to Hamiltonian coupling, electrons transition from high energy level to low energy level and release photons; Or absorb photons and transition from low energy level to high energy level, thus obtaining the physical process of quantum walking along a straight line under the condition of equal probability. Then, the optical radiation in the quantum walk is mapped into a Gaussian pulse of the electric field, and the Maxwell's equation is solved by the three dimensional finite-difference time-domain method to obtain the spatial electric distributio. Finally, the physical process ofquantum walking on two parallel lines is further discussed, involving some physical properties such as electromagnetic coupling or coherence, quantum state exchange and so on. The electric field coupling between two lines can be calculated by FDTD, which provides a useful tool for the design and analysis of quantum devices.
