利用动力学蒙特卡罗方法计算了里德堡态铷原子的偶极阻塞效应,分析了主量子数和激光功率对偶极阻塞效应的影响.随着主量子数、激光功率增加,偶极阻塞效应随之增强.激光功率足够高时,被激发到里德堡态的原子将趋于饱和.结果表明:通过选择铷原子里德堡态能级和调节激光功率可以操控里德堡原子的偶极阻塞效应,这在制作量子比特及量子信息处理等方面有重要的应用.
The influences of principle quantum number and laser power on dipole blockade effect are analyzed by calculating dipole blockade effect of Rydberg state rubidium atoms with kinetic Monte Carlo method.The dipole blockade effect is enhanced with increasing of the principle quantum number and laser power.When the laser power is high enough,atoms excited to Rydberg state tend to be saturated.Results show that the dipole blockade effect of Rydberg atoms can be controlled by selecting Rydberg states of rubidium atomic energy level and adjusting laser power,which has important applications in producing quantum bits and quantum information processing.
