Studies of the $^{1}$S$_{0}$--$^3$P$_0$ transition in atomic ytterbium for optical clocks and qubit arrays

摘要

We report an observation of the weak $6^{1}$S$_{0}$-$6^3$P$_0$ transition in$^{171,173}$Yb as an important step to establish Yb as a primary candidate forfuture optical frequency standards, and to open up a new approach for qubitsusing the $^{1}$S$_{0}$ and $^3$P$_0$ states of Yb atoms in an optical lattice.
