abstract = "Cryogenic RF transistors and routing circuits operating with extremely low power are essential as control/readout electronics for future large-scale quantum computing (QC) systems. In this work, we demonstrate 3D stackable InGaAs HEMT-based cryogenic RF transistors and routing circuits integrated with Nb superconductors for ultra-low power operation. As a result, we achieve a record high unity current gain cutoff frequency (fT) of 601 GHz and unity power gain cutoff frequency (fMAX) of 593 GHz at 4 K with the smallest power dissipation among ever reported cryogenic RF transistors. Furthermore, using a novel structure with Nb superconductor and III-V heterostructure hybrid interconnect of the routing circuits, we achieve high-performance routing circuits with 41\% lower power dissipation compared to the conventional structure.",
