项目摘要

The object of our group is to study quantum mechanical interactions between matter and light in a simple system and to provide support for other groups working with micro-spheres and semiconductors. The technique by Ohtsu et al on the optical fiber tips contributed to the progress of the works that use SNOM technique. Theoretical achievements of our group include new proposal of quantum computer elements, Quantum Zeno effect and an extensive analysis of near field optical fields. Kitagawa proposed a quantum computer elements that uses nuclear magnetic resonance of organic molecules and designed the method to extract the computed results by using parity gates. Kitano discussed the relation between the quantum Zeno effeet and adiabatic evolution of a auantum system. Cho et al discussed in detail near field optical response of materials from the first principle. They gave a generalized formulae that can be applied to the soliton theory, dynamic diffration of X-ray and photonic band theory. The theory contributed to the theoretical analysis of experimental works of other groups. On the experimental side, Inoue et al produced for the first time a two-dimensional photonic band crystal in one micron wavelength region and observed new laser action with a doped crystal. They developed also three dimensional photonic band crystals in microwave region with silicon crystals. Shimizu et al worked with laser-cooled metastable neon atoms. They studied dynamics of optical lattices, quantum statistical characteristics of ultra-cold collisions and two atom correlation spectra. They developed also microwave lens for neutral atomic beam and atom holography.

我们小组的目的是研究简单系统中物质和光之间的量子机械相互作用，并为使用微电脑和半导体的其他组提供支持。 Ohtsu等人在光纤尖端上的技术有助于使用SNOM技术的作品的进步。我们小组的理论成就包括新的量子计算机元素的建议，量子ZENO效应以及对近场光场的广泛分析。 Kitagawa提出了一种使用有机分子的核磁共振的量子计算机元件，并设计了使用奇偶校验门提取计算结果的方法。基塔诺（Kitano）讨论了量子系统的量子Zeno Effet与绝热的演变之间的关系。 Cho等人详细讨论了第一个原理的材料的光学响应。他们给出了一个广义公式，可以应用于孤子理论，X射线和光子带理论的动态衍射。该理论有助于对其他群体的实验工作进行理论分析。在实验侧，Inoue等人首次在一个微米波长区域中产生了二维光子带晶体，并观察到具有掺杂晶体的新激光作用。他们还在带有硅晶体的微波区域中开发了三维光子带晶体。 Shimizu等人与激光冷却的亚稳态霓虹原子合作。他们研究了光学晶格的动力学，超冷碰撞的量子统计特征和两个原子相关光谱。他们还开发了用于中性原子束和原子全息图的微波镜头。
