使用代数动力学方法,对激光-二能级原子系统的含时薛定谔方程进行求解.该系统哈密顿量具有SU(2)代数结构,得到了严格解。基于严格解,适当调节单模激光场的频率和振幅以及短脉冲激光与二能级原子的二阶虚光子作用强度,可实现一位通用量子逻辑门。
The time dependent Schroedinger Equation of a laser-two-level-atom system has been solved by algebraic dynamics method. The exact analytical solution is obtained, and the single qubit logical gate can be realized through adjusting the amplitude and frequency of the single mode laser field as well as strength of the short pulse laser field.
