Abstract
Aspects of the present disclosure relate generally to parallel sideband cooling of multiple trapped-ion motional modes with deflectors (e.g., acousto-optic deflectors or AODs) in quantum information processing (QIP) systems. A method and a system are described in which for an ion chain a first group of ions (e.g., middle section of the ion chain) and a second group of ions (e.g., outer sections of the ion chain) are identified. The method and system include performing sideband cooling by applying, to the first group of ions, a first pair of optical beams using a first pair of AODs, and applying, to the second group of ions, a second pair of optical beams using a second pair of AODs. For each AOD, an acousto-optic modulator (AOM) may be placed upstream to provide frequency modulation for matching frequency differences for correct detuning as part of the sideband cooling operation.
