Fast polarimetry system for the application to spin quantum non-demolition measurement

Autor: Takeuchi, M., Takano, T., Ichihara, S., Yamaguchi, A., Kumakura, M., Yabuzaki, T., Takahashi, Y.

We report the development of a fast pulse polarimeter for the application to quantum non-demolition measurement of atomic spin (Spin QND). The developed system was tunable to the atomic resonance of ytterbium atom and has narrow laser linewidth suita

Paramagnetic Faraday rotation with spin-polarized ytterbium atoms

Autor: Takeuchi, M., Takano, T., Ichihara, S., Takasu, Y., Kumakura, M., Yabuzaki, T., Takahashi, Y.

We report observation of the paramagnetic Faraday rotation of spin-polarized ytterbium (Yb) atoms. As the atomic samples, we used an atomic beam, released atoms from a magneto-optical trap (MOT), and trapped atoms in a far-off-resonant trap (FORT). S

Spin Squeezing via One-Axis Twisting with Coherent Light

Autor: Takeuchi, M., Ichihara, S., Takano, T., Kumakura, M., Yabuzaki, T., Takahashi, Y.

We propose a new method of spin squeezing of atomic spin, based on the interactions between atoms and off-resonant light which are known as paramagnetic Faraday rotation and fictitious magnetic field of light. Since the projection process, squeezed l
