    3D interconnects and multi-module integrated surface electrode ion trap for scalable quantum information processing by Zhao, Peng

    Published 2022
    “…In terms of the ion trapping performance, both the heating rate (17 quanta/ms for an axial frequency of 300 kHz) and the lifetime (~30 minutes) of TSV trap are comparable with non-cryogenic traps of similar dimensions. Moreover, a customized CPGA with patterned redistribution layer is used to locate TSV integrated trap directly in the absence of glass interposer, facilitating high-efficiency thermal management and upgrading the packaging flexibility. …”
