The Trapped Ion Frequency Standard: Current Status and Future Prospects

Eric Cornell

Günter Werth

Present experiments on ion trap frequency standards in the microwave, optical and infrared spectral regions are described, and new ions are considered with respect to their potential as possible candidates. The present status strongly suggests that fractional frequency instabilities of about 10-16 will soon be obtained. Furthermore miniaturization of practical devices seems possible in the near future.

Individually trapped 137Ba+ in an RF Paul trap is proposed as a qubit candidate, and its various benefits are compared to other ionic qubits. We report the current experimental status of using this ion for quantum computation. Future plans and prospects are discussed.
