Characterization of Cryo-CMOS heating and noise properties using Silicon spin qubits

ORAL

Abstract

Cryo-CMOS has previously been demonstrated as a promising control interface for large-scale spin qubit quantum computation. However, its substantial heat dissipation has limited its integration to the 4K stage of a dilution fridge. In this talk, we employ an approach developed earlier in our group [1], utilizing Cryo-CMOS at an ultra-low temperature of 20 mK. Leveraging spin qubits as probing tools, we conduct a comprehensive examination of the Cryo-CMOS chip's thermal and noise properties and their concurrent impact on spin qubits across a wide parameter space. Our findings provide valuable insights for enhancing cryo-CMOS technology, particularly in the context of its heterogeneous integration with silicon spin qubits, advancing the prospects of quantum computing architectures.
