Abstract
An operating method for stimulated Raman adiabatic passage to change probability amplitude in a three-level system including states of |0>, |1> and |e>, includes the following two steps. One is to direct a first laser beam and a second laser beam which have frequencies in the vicinity of resonance frequencies corresponding to energy differences between |0> and |e> and between |1> and |e>, respectively. The other is to change temporally two-photon detuning to be a difference between first detuning and second detuning. The first detuning is a difference between a first energy difference and a frequency of the first laser beam. The first energy difference is a difference between energy of |0> and energy of |e>. The second detuning is a difference between a second energy difference and a frequency of the second laser beam. The second energy difference is a difference between energy of |1> and energy of |e>.
