Suppressing On-Chip EM Crosstalk for Spin Qubit Devices

Mesoscale and Nanoscale Physics 2015-09-24 v1 Quantum Physics

Abstract

We report the development and performance of on-chip interconnects designed to suppress electromagnetic (EM) crosstalk in spin qubit device architectures with the large number of gate electrodes needed for multi- qubit operation. Our design improves the performance of typical device interconnects via the use of minia- turised ohmic contacts and interspersed ground guards. Low temperature measurements and numerical simulation confirm that control and readout signal crosstalk can be suppressed to levels of order 1%, from dc to 1 GHz.
