| Research Abstract |
While photons do not interact with each other and are difficult to localize, they are the fastest and the most robust carriers of quantum information. In contrast, atoms can interact with each other and can even be stopped by conventional laser cooling techniques, but they cannot be the fast carrier of the information. We can cancel the disadvantages of both systems and utilize only advantages if quantum information of lights can be coherently transferred to the atoms. The results of the research are as follows.
(1) Theoretical proposal of ultra slow light propagation without EIT,
(2) Experimental realization of ultra slow light propagation without EIT,
(3) Coherent transfer of orbital angular momentum from an atomic system to light field,
(4) Theoretical proposal of giant non-linear effect induced by ultra slow light propagation,
(5) Manipulating orbital angular momentum of light with storage of light and quantum phase imprinting methods,
(6) Observation of photon statistics for ultraslow and stored light pulses.
