The coherent storage and phase modulation of x-ray single-photon wave packets in the resonant scattering of light off nuclei is theoretically investigated. We show that by switching off and on again the magnetic field in the nuclear sample, phase-sensitive storage of photons in the keV regime can be achieved. Corresponding π phase modulation of the stored photon can be accomplished if the retrieving magnetic field is rotated by 180°. The development of such x-ray single-photon control techniques is a first step towards forwarding quantum optics and quantum information to shorter wavelengths and more compact photonic devices.
本文理论研究了在光与原子核的共振散射中，对 X 射线单光子波包的相干存储和相位调制。研究表明，通过在核样本中关闭和再次打开磁场，可以在 keV 量级实现对光子的相位敏感存储。如果检索磁场旋转 180°，则可以实现存储光子的π相调制。这种 X 射线单光子控制技术的发展是将量子光学和量子信息推进到更短的波长和更紧凑的光子器件的第一步。
