We have successfully developed a high-sensitive measurement system for current fluctuation in mesoscopic systems, which was applied to measure the dynamical transport through various semiconductor nanostructures such as electron interferometers, quantum dots, and quantum wires. These nanostructures are recently envisaged to be a nice stage to create and detect electronic entanglement. We demonstrated the first experimental test of "fluctuation theorem" in quantum regime and the generation of the polarized nuclear systems. Our achievement convincingly confirms that the precise noise measurement is indispensible to address the entanglement and the nonequilibrium transport phenomena.
