Outline of Final Research Achievements

We developed a technique to control stably and coherently the spin-states of atomic ensemble (Bose-Einstein condensate) trapped above a superconducting atom chip using radio, microwave, and infrared light fields. Since this technique can be applicable for recording superposition of atomic spin states, we proposed a scheme for realizing a security enhanced quantum memory using atomic ensemble, and succeeded in the demonstration of it. Moreover, we demonstrated the quantum memory for photons with an atomic ensemble, and succeeded in observing non-classical correlations between the recorded atomic spin state and the heralding photon state after the frequency conversion and transportation via an optical fiber.
