Dynamical suppression of spontaneous emission in two-level atom

  title={Dynamical suppression of spontaneous emission in two-level atom},
  author={Wang Zhong-jie},
Dynamical control of decoherence induced by the environment in a twolevel atom system is investigated.We choose the suitable perturbations acting on the qubit system to decrease the decoherence due to spontaneous emission damping.The scheme proposed here is based on the frequency-displacement technique and the parity-kick technique,which are realized by two homogeneous classical large detuned optical fields with different frequencies added to the system.By applying this scheme,in presence of… CONTINUE READING
