Measurement schemes for the spin quadratures on an ensemble of atoms
Ryo Namiki, Tetsushi Takano, Shin-Ichi-Ro Tanaka +1
We consider how to measure collective spin states of an atomic ensemble based on the recent multi-pass approaches for quantum interface between light and atoms. We find that a sche…
A scalable quantum computer with an ultranarrow optical transition of ultracold neutral atoms in an optical lattice
K. Shibata, S. Kato, A. Yamaguchi +2
We propose a new quantum-computing scheme using ultracold neutral ytterbium atoms in an optical lattice. The nuclear Zeeman sublevels define a qubit. This choice avoids the natural…
Fast polarimetry system for the application to spin quantum non-demolition measurement
M. Takeuchi, T. Takano, S. Ichihara +4
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 a…
Paramagnetic Faraday rotation with spin-polarized ytterbium atoms
M. Takeuchi, T. Takano, S. Ichihara +4
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-opti…
