摘要： 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>.

摘要： PROBLEM TO BE SOLVED: To provide a waveform of an optical pulse most suitable for execution of population transfer based on STIRAP. SOLUTION: According to one embodiment of the invention, a quantum information processing method and apparatus transfers a state of a physical system having two spin-down states ¾0> and ¾1> and one spin-down state ¾2>, from ¾0> to ¾1> in a transfer time T by irradiating the physical system with two pulses (hereafter, a pulse 0 and a pulse 1) resonating with transition from ¾0> to ¾2> and transition from ¾1> to ¾2>. The pulses are temporally changed sufficiently more slowly than their Rabi frequencies and a quantum state is adiabatically changed in a center portion of the transfer time, and the quantum state is non-adiabatically changed properly in start and end portions of the transfer time, so that the probability of the existence of the spin-up state ¾2> in the adiabatic change in the center portion can be minimized.

摘要：第1の方向に互いに積層された複数の誘電体層を備え、前記複数の誘電体層のそれぞれの厚さは、設計波長の1/2の長さであり、前記複数の誘電体層のうちのいずれかは、厚さが前記設計波長の1/8であり、第1部分屈折率を有する第1部分と、前記第1部分と積層され、厚さが前記設計波長の1/8であり、前記第1部分屈折率よりも低い第2部分屈折率を有する第2部分と、前記第1部分と前記第2部分との間に設けられ、厚さが前記設計波長の1/4であり、前記第1部分の側から前記第2部分の側に向かうに従って漸減する第3部分屈折率を有する第3部分と、を有し、前記第3部分屈折率の厚さ方向に関する分散が、前記第1部分屈折率の厚さ方向に関する分散及び前記第2部分屈折率の厚さ方向に関する分散よりも大きいことを特徴とするミラーが提供される。これにより、低損失で高反射のミラーが提供できる。
