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.

Abstract: Aspects of the present disclosure describe devices trapping devices for use in quantum information processing (QIP) architectures, and more particularly, to the use and fabrication of a multi-layer ion trap on shaped glass or dielectric substrate. A method for fabricating the ion trap is described that includes preparing a back surface of the substrate, building a multi-layer stack on the top surface of the substrate, and completing the back etch to break through the substrate and etching through a metal and dielectric in the multi-layer stack to complete the formation of the ion trap.

Abstract: The use of multiple ion chains in a single ion trap for quantum information processing (QIP) systems is described. Each chain can have its own set of laser beams with which to implement and operate quantum gates within that chain, where each chain may therefore correspond to a single quantum computing register or core. Operations can be performed in parallel across all of these chains as they can be treated independently from each other. To implement and operate quantum gates between different chains, neighboring chains are merged into a single, larger chain, in which one can perform quantum gates between any of the ions in the larger chain. The combined chains can then be separated again by another shuttling event as needed. To implement and operate quantum gates between ions which do not occupy neighboring chains, swap gates can be used via a sequence of intervening chains.
