Towards quantum logic spectroscopy of multi-ion arrays
ORAL
Abstract
We describe a new approach for precision spectroscopy of trapped ions using quantum logic. Our approach adapts method developed in the context of quantum information processing to non-destructive detection of the 1S0-3P0 clock transition in 27Al+. A state-dependent force is employed on the spectroscopy ion(s) to modulate the qubit state of the detection ion(s), similar to the techniques employed for high-fidelity quantum gates[1,2] and sensitive force detection experiments [3,4]. This method does not require ground state cooling and would enable scaling to large numbers of spectroscopy ions to improve ion clock stability.
