Voltage-controlled quantum dynamics of two quantum-dot molecules (QDMs) embedded in two separated photonic crystal cavities are theoretically investigated. We show numerically that generation of entangled states and population transfer between the two QDMs can be realized with the same coupling parameters. The effects of parameters deviation and dissipations on generation entangled states be used for realization of new-type of solid state quantum and populations transfer are also discussed. The results may devices and integrated electro-optical devices, 相似文献

在碱性条件下用NaBH4还原氧化石墨烯(GO),成功制备水分散性良好的石墨烯。用制备的石墨烯修饰玻碳电极,并通过循环伏安法(CV)和差分脉冲伏安法(DPV)研究了福莫特罗酒石酸盐在该修饰电极上的电化学行为。优化DPV条件下,福莫特罗酒石酸盐的氧化峰电流与浓度在3.64×10-7~1.64×10-4 mol·L-1范围内呈线性关系(r=0.9978),检出限为7.89×10-8 mol·L-1。电化学测试结果表明,石墨烯修饰玻碳电极具有响应时间快、重现性和稳定性好的特点,可用于福莫特罗酒石酸盐的检测。 相似文献
