Development of Novel Quantum Manipulation and Measurement Methods using Ultranarrow-Linewidth Lasers

Research Project Outline

We develop ultrastable lasers with the linewidths of a few Hertz and even sub-Hertz.Through the application ofsuch lasers to laser-cooled two-electron atoms in an optical lattice, we establish novel quantum manipulation and measurement technique for asingle atom in an optical lattice by exploiting an optical magnetic resonance imaging method as well as a novel quantum measurement scheme utilizing a spin-squeez-ing technique. With these innovations we will realize a proto-type of optical lattice quantum computer and an optical lattice clock with increased precision.
