A토토 승무패mic Clocks,

야구 토토s are studied being closely, almost inseparably, related with light. The simple symmetries and regular motions of 야구 토토s are often used to probe the precise properties of light, and also various new phenomena of 야구 토토s are created, probed, and applied by light. In particular, 야구 토토 cooling and trapping by laser enabled extreme cold matters in temperature below 10^-12 Kevin, and also ultra-precise clocks with uncertainty of below 10^-18.� In this talk prepared for undergraduate and graduate students majoring physics, I present two experiments from our lab, related with the laser 야구 토토 cooling and trapping. First one is to use laser to sequentially modify the 야구 토토ic states to use the 야구 토토-laser combination in a way of processing the quantum information (qubit), and the second is to arrange the 야구 토토s in space and rearrange them by light.
