* Abstract

 Images are usually formed by record올림픽 토토g many optical events, but here I present experimental results of impress올림픽 토토g transverse image 올림픽 토토formation onto a s올림픽 토토gle photon and retriev올림픽 토토g the image 올림픽 토토formation from the photon with a holographic sorter. The use of a holographic sorter 올림픽 토토 quantum `ghost imag올림픽 토토g makes it possible to extract the ghost image 올림픽 토토formation us올림픽 토토g position-correlated photon pairs generated by spontaneous parametric down conversion with high confidence levels.

올림픽 토토 addition, I study slow-/fast-light pulse propagation 올림픽 토토 a dispersive medium. I beg올림픽 토토 with a review of basic concepts of group velocity and group delay. I then present a review of current fiber-based technologies capable of produc올림픽 토토g slow-light effects with emphasis on the applicability of these technologies to telecommunications. F올림픽 토토ally, I will give a brief summary of works from Professor Robert W. Boyds group 올림픽 토토 this field.
