AI+ Optical Frequency Standard and Ion Trap Development
Abstract
The goal of the proposed project is to substantially improve the performance of state-of-the-art trapped-ion optical frequency standards (clocks) based on quantum-logic spectroscopy of aluminum ions (Al+), and to develop new types of ion traps to be used both for clocks and for other applications such as quantum information processing and quantum-limited metrology. Specifically, we aim to improve the accuracy of Al+ clocks by performing an improved characterization of systematic frequency shifts related to imperfections of the ion traps used toconfine the ions, and we aim to improve the stability of optical clock measurements by taking advantage of correlated noise in clock comparison measurements using a technique called correlation spectroscopy and increasing the number of Al+ ions. Correlation spectroscopy has been used in the past to measure the frequency difference of two ions in a single ion trap, but the proposed project would be the first time it is used to measure the frequency difference of two spatially separated and independent clocks. The combination of implementing correlation spectroscopy and increasing the number of ions should allow us to reduce the time required forclock measurements by a factor of 20.
